Comcast

History

American Cable Systems

In 1963, Ralph J. Roberts in conjunction with his two business partners, Daniel Aaron and Julian A. Brodsky, purchased American Cable Systems as a corporate spin-off from its parent, Jerrold Electronics, for U.S. $500,000. At the time, American Cable was a small cable operator in Tupelo, Mississippi, with five channels and 12,000 customers. In 1965, American Cable Systems purchased Storecast Corporation of America, a product placement supermarket specialist marketing firm. In 1968, American Cable Systems purchased its first franchise of Muzak, a brand of background music played in retail stores. Storecast was a client of Muzak.

Comcast

The company was re-incorporated in Pennsylvania on March 5, 1969, under the new name Comcast Corporation. Comcast's initial public offering occurred on June 29, 1972, on the National Association of Securities Dealers Automated Quotation System (NASDAQ), a then-recently established stock exchange, with a market capitalization of U.S. $3,010,000. In 1977, HBO was first launched on a Comcast system with 20,000 customers in western Pennsylvania with a five-night free preview getting a 15% sign up rate. In 1986, Comcast bought 26% of Group W Cable, a broadcast company, doubling its number of subscribers to 1 million. Also that year, Comcast made a founding investment of $380 million in QVC. In 1988, Comcast was able to buy a 50% share of SCI Holdings in a joint deal with Tele-Communications Inc. Comcast also acquired American Cellular Network Corporation in 1988 for $230 million, marking the first time it became a mobile phone operator.

Increasing market share (1990–2001)

In February 1990, Ralph Roberts' son, Brian L. Roberts, succeeded his father as president of Comcast. Ralph Roberts established The Comcast Fund, a foundation that supports innovative ideas and research in technology and public policy. Daniel Aaron retired, although he remained on the company's board. Two years later, the company's mobile division, Comcast Cellular, purchased a controlling interest in Metromedia's Philadelphia-area cellular telephone interests, Metrophone. By 1994, Comcast owned 50% stock in the cable communications company Garden State Cable, who by that year were serving approximately 195,000 subscribers. That same year, Comcast became the third-largest cable operator in the United States, with around 3.5 million subscribers following its purchase of Maclean-Hunter's American division for $1.27 billion. Comcast grew to 4.3 million subscribers the following year with the purchase of the cable operation of E. W. Scripps Company for $1.575 billion in stock.

Comcast offered internet connection for the first time in 1996, with its part in the launch of the @Home Network. Also in 1996, Comcast formed Comcast Spectacor, which became owner of the Philadelphia Flyers. In 1997, Microsoft invested $1 billion in Comcast, and the company launched its digital television service. That same year, in partnership with The Walt Disney Company, Comcast got a 50.1% controlling interest in E! Entertainment. By December 31, 1997, it was available in the Philadelphia, Detroit, Baltimore, Orange County, California, Sarasota and Union, New Jersey areas.

Comcast's cable acquisitions in 1997 were Jones Intercable, Inc. with 1 million customers, and a stake in Prime Communications with 430,000 subscribers. In February 1998, Comcast sold its U.K. division to NTL for US$600 million, along with the division's $397 million in debt. In 1999, Comcast sold Comcast Cellular to SBC Communications for $400 million, releasing it from $1.27 billion in debt. Also in 1999, Comcast acquired Greater Philadelphia Cablevision, and launched Comcast University as well as Comcast Interactive Capital Group.

In November 1999, Comcast purchased Lenfest Communications, who were the ninth largest cable television operator at the time and were the largest operator in the Philadelphia area. This consolidated Comcast's control over all of the Philadelphia region, and earned it approximately 1.3 million additional cable subscribers. The purchase of Lenfest also bought Comcast the remaining 50% stock of the cable operator Garden State Communications — a company whom Comcast had already owned half of in partnership with Lenfest for years. Comcast quickly replaced the ten-year general manager at Garden State with their own executive, and eventually Garden State ceased operating under its own name and was fully merged to become a part of the Comcast Corporation.

Largest American cable provider (2001–present)

In 2001, Comcast announced it would acquire the assets of the largest cable television operator at the time, AT&T Broadband, for $44.5 billion. The proposed name for the merged company was "AT&T Comcast", but the companies ultimately decided to keep only the Comcast name, with the company and new assets reincorporated in Pennsylvania on December 7, 2001. On November 18, 2002, Comcast officially acquired all assets of AT&T Broadband, thus making Comcast the largest cable television company in the United States with over 22 million subscribers. This spurred the start of Comcast Advertising Sales (using AT&T's groundwork) which would later be renamed Comcast Spotlight, then Effectv, A Comcast Company and is now known as Comcast Advertising. As part of this acquisition, Comcast also acquired the National Digital Television Center in Centennial, Colorado as a wholly owned subsidiary, now known as the Comcast Media Center. In 2003, Comcast became one of the original investors in The Golf Channel. After Excite@Home went bankrupt in October 2001, Comcast took over providing internet directly to consumers in January 2002.

On February 11, 2004, Comcast announced a $54 billion bid for Disney, including taking on $12 billion of Disney's debt. The deal would have made Comcast the largest media conglomerate in the world. However, after rejection by Disney and uncertain response from investors, the bid was abandoned in April. In 2004, Comcast sold its QVC shares to Liberty Media for $7.9 billion.

On April 8, 2005, a partnership led by Comcast and Sony Pictures Entertainment finalized a deal to acquire MGM and its affiliate studio, United Artists, and created an additional outlet to carry MGM/UA's material for cable and Internet distribution. On October 31, 2005, Comcast officially announced that it had acquired Susquehanna Communications, a South Central Pennsylvania-based cable television and broadband services provider and unit of the former Susquehanna Pfaltzgraff company, for $775 million cash. Comcast previously owned approximately 30% of Susquehanna Communications through its affiliate company, Lenfest. In December 2005, Comcast announced the creation of Comcast Interactive Media, a new division focused on online media.

In July 2006, Comcast purchased the Seattle-based software company thePlatform. This represented an entry into a new line of business—selling software to allow companies to manage their Internet (and IP-based) media publishing efforts.

Divisions and subsidiaries

Comcast Cable (Xfinity)

Comcast Cable, which goes by the brand name Xfinity, provides cable television, broadband internet, and home telephone services. Comcast Cable also provides similar services to small to medium-sized businesses through its Comcast Business brand, and Fortune 1000 companies through its Comcast Enterprise brand.

NBCUniversal

Comcast delivers third-party television programming content to its own customers, and also produces its own first-party content both for subscribers and customers of other competing television services. Fully or partially owned Comcast programming includes Comcast Newsmakers, Comcast SportsNet and SportsNet New York. On May 19, 2009, Disney and ESPN announced an agreement to allow Comcast Corporation to carry the channels ESPNU and ESPN3.

Comcast's content networks and assets also include Bravo, NBCSN and the regional NBC Sports Networks. When Comcast took majority ownership of NBCUniversal, a significant number of cable networks were added to this list. Comcast's NHL deal obligated it to create a U.S. version of NHL Network, launched in October 2007.

Comcast has also operated local channels in some markets, such as Comcast Television in the Detroit region, Comcast Network in the Philadelphia and Mid-Atlantic regions (formerly CN8), and Comcast Entertainment Television in Denver and parts of Utah. They primarily carried local programs and sports (including, in some cases, serving as the designated overflow channel for local regional sports networks).

On August 22, 2016, NBCUniversal bought DreamWorks Animation along with its major IP, including Shrek, How to Train Your Dragon, Kung Fu Panda, Trolls, and Madagascar, included in the acquisition was Classic Media, which included a wide library of IP including Postman Pat, Felix the Cat, Noddy, Rudolph the Red-Nosed Reindeer, Frosty the Snowman, Turok, Casper the Friendly Ghost, VeggieTales among a number of others.

Sky Group

Through Sky, Comcast offers any first-party and third-party television programming which using the satellite distribution and IPTV (Sky Glass and Sky Stream) systems to its customers and subscribers across several countries in Europe, such as the United Kingdom, Ireland, Germany, Austria, Switzerland, and Italy. It is Europe's largest media company and pay-TV broadcaster by revenue (as of 2018), with 23 million subscribers and more than 31,000 employees as of 2019.

Until November 2018, Sky was owned by 21st Century Fox through a 39.14% controlling stake; on 9 December 2016, following a previous attempt under News Corporation that was affected by the News International phone hacking scandal, 21st Century Fox announced that it had agreed to buy the remainder of Sky, pending government approval. However, after a bidding war that included Disney (which was, in turn, acquiring most of 21st Century Fox assets), Comcast acquired the entirety of Sky in 2018 for £17.28 per-share.

In 2020, NBCUniversal and Sky Group began preparations to launch an international news channel called NBC Sky World News. The service was also planned for it to be available on Peacock in the United States. Plans for the launch – initially scheduled for summer 2020 – were put on hold due to the COVID-19 pandemic in the United Kingdom. and in August, the proposed service was scrapped, resulting in layoffs of 60 employees. NBC subsequently allowed its free streaming service NBC News Now to be seen internationally, and is available globally on YouTube and on Sky TV and Virgin Media in the UK.

Since its acquisition by Comcast, Sky has faced a series of financial woes. Bought for £31 billion, Sky's value has been written down by nearly 25%. In 2023, operating losses doubled as Sky reported a pre-tax loss of £773 million ($1.045 billion). Sky News is estimated to lose at least £30 million ($40.57 million) per annum.

Xumo

Xumo is a free ad-supported streaming television (FAST) service, which Comcast acquired on February 25, 2020, for an undisclosed amount. The service operates as a business within the Comcast Cable division. Comcast planned to position the service as a complement to its premium streaming service Peacock (as well as compete with ViacomCBS's Pluto TV and Fox Corporation's Tubi), and leverage its streaming technology, as well as its distribution partnerships with smart TV manufacturers.

On October 19, 2021, Comcast announced "XClass TV", a line of smart TVs manufactured by Hisense that would be powered by the X1 software platform used by its cable services.

In April 2022, Comcast and Charter Communications announced that they would form a joint venture to form a "next-generation streaming platform", with Comcast contributing its Xfinity Flex, XClass TV, and Xumo businesses. In November 2022, Comcast and Charter announced that the joint venture would use the Xumo name, with Xumo, Xfinity Flex, and XClass TV rebranded as Xumo Play, Xumo Stream Box, and Xumo TV respectively.

In June 2024, Comcast signed a deal with Fubo to make the streaming service available to its Xfinity Flex or Xumo Stream Box customers, as well as Xumo TVs.

Professional sports

In 1996, Comcast bought a controlling stake in Spectacor from the company's founder, Ed Snider. Comcast Spectacor holdings now include the Philadelphia Flyers NHL hockey team and their home arena in Philadelphia, as well as esports organization T1, in a joint venture with South Korea's SK Telecom. Over a number of years, Comcast became the majority owner of Comcast SportsNet, as well as Golf Channel and NBCSN (formerly the Outdoor Life Network, then Versus). In 2002, Comcast paid the University of Maryland $25 million for naming rights to the new basketball arena built on the College Park campus, the Xfinity Center. Before it was renamed for Comcast's cable subsidiary, Xfinity Center was called Comcast Center from its opening in 2002 through July 2014. Comcast became the sponsor of NASCAR's second-tier series in 2015, renaming it the NASCAR Xfinity Series.

Corporate affairs

Leadership

Comcast is described as a family business. Brian L. Roberts, its chairman and CEO, is the son of founder Ralph J. Roberts (1920–2015). Roberts owns or controls about 1% of all Comcast shares but all of the Class B supervoting shares, giving him an "undilutable 33% voting power over the company". Legal expert and critic Susan P. Crawford has said this gives him "effective control over [Comcast's] every step". In 2010, he was one of the highest-paid executives in the United States, with total compensation of about $31 million.

Corporate offices

Comcast is headquartered in Philadelphia, Pennsylvania, and has offices in Atlanta, Detroit, Denver, Manchester, New Hampshire and New York City. On January 3, 2005, it announced it would become the anchor tenant in the new Comcast Center in downtown Philadelphia—at 975 ft (297 m), the second-tallest skyscraper in Pennsylvania. In the fall of 2018, it finished construction of the 1,121 ft (342 m) Comcast Technology Center, Pennsylvania's tallest skyscraper, adjacent to its original headquarters. As of 2019, the company had 184,000 employees.

Employee relations

Comcast is often criticized by the media and its own staff for its less-than-upstanding policies of employee relations.

A 2014 investigative series published by The Verge involved interviews with 150 Comcast employees and examined why the company was so widely criticized by its customers, the media, and its own workers. It concluded that Comcast's staff endured unreasonable corporate policies: "Customer service has been replaced by an obsession with sales; technicians are understaffed ... tech support is poorly trained, and the company is hobbled by internal fragmentation." A widely read article by an anonymous Comcast call center employee appeared in November 2014 on Cracked. Titled "Five Nightmares You Live While Working For America's Worst Company", it claimed that Comcast was obsessed with sales, did not train its employees properly, and concluded that "the system makes good customer service impossible."

Comcast has also earned a reputation as anti-union. A company training manual says, "Comcast does not feel union representation is in the best interest of its employees, customers, or shareholders". A dispute in 2004 with CWA, a labor union representing many employees at Comcast's Beaverton, Oregon offices, led to allegations of management intimidating workers, requiring them to attend anti-union meetings and unwarranted disciplinary action for union members. In 2011, Comcast received criticism from Writers Guild of America for its policies regarding unions.

Despite these criticisms, Comcast has appeared on multiple "top places to work" lists. In 2009, it was included on CableFAX magazine's "Top 10 Places to Work in Cable", which cited its "scale, savvy and vision". Similarly, the Philadelphia Business Journal awarded Comcast the silver medal among extra-large companies in Philadelphia, with the gold medal going to partner organization, Comcast-Spectacor. The Boston Globe found Comcast to be that city's top place to work in 2009. Employee diversity is also an attribute upon which Comcast receives strong marks. In 2008, Black Enterprise magazine rated Comcast among the top 15 companies for workforce diversity.

Financial performance

Comcast reported a net profit in each year during the period 2006 to 2022.

As of 2020, the company was ranked 28th on the Fortune 500 rankings of the largest United States corporations by total revenue.

For the fiscal year 2022, Comcast reported earnings of US$15.4 billion, a decrease of 6.2% compared to the prior year. Annual revenue increased by 4.3% over the same period. Their net debt was $91.2 billion, exceeding total shareholders' equity of $80.9 billion as of December 31, 2022.

Lobbying and electoral fundraising

With $18.8 million spent in 2013, Comcast has the seventh largest lobbying budget of any individual company or organization in the United States. Comcast employs multiple former U.S. Congressmen as lobbyists. The National Cable & Telecommunications Association, which has multiple Comcast executives on its board, also represents Comcast and other cable companies as the fifth largest lobbying organization in the United States, spending $19.8 million in 2013. Comcast was among the top backers of Barack Obama's presidential runs, with Comcast vice president David Cohen raising over $2.2 million from 2007 to 2012. Cohen has been described by many sources as influential in the U.S. government, though he is no longer a registered lobbyist, as the time he spends lobbying falls short of the 20% which requires official registration.

Comcast's PAC, the Comcast Corporation and NBCUniversal Political Action Committee, is among the largest PACs in the U.S., raising about $3.7 million from 2011 to 2012 for the campaigns of various candidates for office in the United States Federal Government. Comcast is also a major backer of the National Cable and Telecommunications Association Political Action Committee, which raised $2.6 million from 2011 to 2012. Comcast spent the most money of any organization in support of the Stop Online Piracy and PROTECT IP bills, spending roughly $5 million to lobby for their passage.

Comcast also backs lobbying and PACs on a regional level, backing organizations such as the Tennessee Cable Telecommunications Association and the Broadband Communications Association of Washington PAC. Comcast and other cable companies have lobbied state governments to pass legislation restricting or banning individual cities from offering public broadband service. Municipal broadband restrictions of varying scope have been passed in a total of 20 U.S. States.

According to watchdog group Documented, in 2020 Comcast contributed $200,000 to the Rule of Law Defense Fund, a fund-raising arm of the Republican Attorneys General Association that was shown to have provided funding to the Save America March that devolved into an attack on the U.S. Capitol on January 6, 2021.

In 2025, Comcast was one of the donors who funded the White House's East Wing demolition and planned building of a ballroom.

Philanthropy

Comcast offers low-cost internet and cable service to schools, subsidized by general broadband consumers through the U.S. government's E-Rate program. Critics have noted that many of the strongest supporters of Comcast's business deals have received substantial funding from the Comcast Foundation. However, for years, Comcast has been relying on subsidiaries to finance philanthropic pursuits.

Cybersecurity incidents

May 28–29, 2008 Comcast.net hijacking

On May 28–29, 2008, the hacker group Kryogeniks, including James Robert Black Jr. (aka "Defiant"), Christopher Allen Lewis ("EBK"), and Michael Paul Nebel ("Slacker"), redirected traffic from Comcast.net-including webmail and voicemail-by taking control of Comcast's domain via its registrar, Network Solutions. The attackers used Social engineering (security) (two phone calls) and a compromised Comcast email account to change domain contact information and alter the domain's DNS settings, resulting in Comcast customers being redirected to a webpage showing a message asserting responsibility ("KRYOGENIKS Defiant and EBK RoXed COMCAST sHouTz to VIRUS Warlock elul21 coll1er seven."). The outage lasted approximately five hours and caused an estimated loss of $128,000 USD to Comcast. Black was later sentenced in 2010 to four months in prison, house arrest/electronic home monitoring, 150 hours of community service, supervised release, and restitution.

July 2015 Aptean SupportSoft vulnerability affecting Comcast

In July 2015, security researchers Blake Welsh and Eric Taylor discovered a cross-site scripting (XSS) vulnerability in Aptean's SupportSoft customer support software, which was used by Comcast. The flaw allowed malicious code to be injected via manipulated URLs, enabling the display of fake login pages that could be used for phishing attacks. Comcast was among the companies tested and notified of the issue.

2015 password reset incident

In November 2015, Comcast required approximately 200,000 customers to reset their passwords after email and password combinations were discovered for sale online. The company stated its internal systems were not breached and that the compromised credentials were likely obtained from other breaches, phishing, or malware.

2016 Xfinity Home security system flaws

In January 2016, researchers at Rapid7 disclosed flaws in Comcast's Xfinity Home security system. The vulnerabilities allowed attackers to disrupt communications between sensors and the central hub using radio jamming, potentially preventing the detection of intrusions. The system also failed to alert users when communications were lost.

2023 Xfinity CitrixBleed data breach CVE-2023-4966

In December 2023, Comcast disclosed that approximately 35.9 million Xfinity accounts had been affected by exploitation of a Citrix NetScaler Vulnerability (computer security), known as "CitrixBleed" (CVE-2023-4966). Exposed information included usernames, encrypted passwords, and, for some customers, dates of birth, contact details, and the last four digits of Social Security numbers. Comcast required password resets and urged customers to enable two-factor authentication.

2024 vendor ransomware exposure (FBCS)

In February 2024, Financial Business and Consumer Solutions (FBCS), a debt collection agency formerly used by Comcast, reported a ransomware attack that exposed information on approximately 237,000 Comcast customers. The exposed data included names, addresses, date of birth, Social Security numbers, and account numbers.

2025 Salt Typhoon espionage reports

In June 2025, U.S. government agencies assessed that Comcast was among several telecommunications providers likely targeted by a Chinese state-linked cyber-espionage group referred to as "Salt Typhoon". Details of the intrusion and whether data was exfiltrated remain unclear.

Criticism and controversies

In 2004 and 2007, the American Customer Satisfaction Index (ACSI) survey found that Comcast had the worst customer satisfaction rating of any company or government agency in the country, including the Internal Revenue Service. The ACSI indicates that almost half of all cable customers (regardless of company) have registered complaints, and that cable is the only industry to score below 60 in the ACSI. Comcast's Customer Service Rating by the ACSI surveys indicate that the company's customer service has not improved since the surveys began in 2001. Analysis of the surveys states that "Comcast is one of the lowest scoring companies in ACSI. As its customer satisfaction eroded by 7% over the past year, revenue increased by 12%." The ACSI analysis also addresses this contradiction, stating that "Such pricing power usually comes with some level of monopoly protection and most cable companies have little competition at the local level. This also means that a cable company can do well financially even though its customers are not particularly satisfied."

In April 2014, Comcast was awarded the 2014 "Worst Company in America" award; an annual contest by the consumer affairs blog The Consumerist that runs a series of reader polls to determine the least popular company in America. This was the second time Comcast had been awarded this title, the first being in 2010.

Comcast spends millions of dollars annually on lobbying. Comcast employs the spouses, sons and daughters of mayors, councilmen, commissioners, and other officials to assure its continued preferred market allocations.

Comcast was given an "F" for its corporate governance practices in 2010, by Corporate Library, an independent shareholder-research organization. According to Corporate Library, Comcast's board of directors' ability to oversee and control management was severely compromised (at least in 2010) by the fact that several of the directors either worked for the company or had business ties to it (making them susceptible to management pressure), and a third of the directors were over 70 years of age. According to The Wall Street Journal, nearly two-thirds of the flights of Comcast's $40 million corporate jet purchased for business travel related to the NBCU acquisition were to CEO Brian Roberts' private homes or to resorts.

On August 1, 2016, Washington State Attorney General Bob Ferguson filed a lawsuit against Comcast Corporation in King County Superior Court, alleging the company's own documents reveal a pattern of illegally deceiving its customers to pad its bottom line by tens of millions of dollars. The FCC issued a $2.3 million fine to Comcast after finding that the company was charging customers for unordered services and equipment. More than a thousand customers issued complaints about these unprecedented charges on their bills. In addition, numerous customers reported inappropriate name-calling and interrogation by customer service representatives. Comcast's executive vice president, David Cohen, admitted the company needed to improve its customer service.

Carbon footprint

Comcast reported total CO2e emissions (direct + indirect) for the twelve months ending 31 December 2020 at 2,291 Kt (-249 /-9.8% y-o-y).
