Comcast Corporation is an American media and technology company with operations in broadband, wireless services, video, business communications, entertainment, film, television, streaming, and theme parks.
Headquartered in Philadelphia, Pennsylvania, its major business units include Xfinity, Comcast Business, NBCUniversal, Telemundo, Peacock, and Sky. Its Class A common stock trades on the Nasdaq stock exchange under the ticker symbol CMCSA. As of 2025, the company had about 179,000 employees worldwide.
Comcast was founded in 1963 by Ralph J. Roberts, Daniel Aaron, and Julian A. Brodsky as a cable television company in Tupelo, Mississippi. In 1969, the company relocated its headquarters to Philadelphia and adopted the name Comcast Corporation. It grew through a series of acquisitions, including Group W Cable in 1986, Storer Communications in 1988, E.W. Scripps in 1995, and Jones Intercable, Inc., in 1999.
The companyâs early expansion culminated in its $44.5 billion acquisition of AT&T Broadband in 2002, which made Comcast the largest cable television operator in the United States.

In 2006, Comcast and Time Warner Cable jointly acquired the assets of Adelphia Communications, one of the nationâs largest cable operators, adding about 1.7 million subscribers to Comcastâs network. Comcast continued to diversify beyond cable television, acquiring the remaining interest in E! Entertainment in 2006 after first purchasing a controlling stake in 1997. It acquired a controlling interest in the Golf Channel in 2001 and purchased the movie-ticketing service Fandango in 2007.
In January 2011, Comcast acquired a 51% stake in NBCUniversal from General Electric. Two years later, it purchased GEâs remaining interest, giving Comcast full ownership of NBCUniversal. Comcast acquired DreamWorks Animation in 2016 and launched Xfinity Mobile cellular service in 2017 under an agreement to use Verizon Communicationsâ (VZ) wireless network. In 2018, Comcast acquired British media and telecommunications company Sky Group, owner of Sky News and one of Europeâs largest pay television providers.
In 2020, Comcast launched Peacock, a streaming service featuring programming from NBCUniversal. The company continued to expand its streaming and digital media ventures, including Xumo, a joint venture with Charter Communications, and SkyShowtime, a European streaming service developed with Paramount Global.
In 2024, Comcast said it intended to spin off several of its cable television networks and related digital media assets into a separate publicly traded company. The next year, Comcast completed the sale of its remaining interest in Hulu to The Walt Disney Company (DIS), ending a long-running joint venture in streaming media.
Later in 2025, Comcast President Michael J. Cavanagh was named co-chief executive officer of the company alongside Chairman Brian L. Roberts, beginning in 2026.
In January 2026, it completed the spin-off of its cable networks and digital media assets, creating Versant Media Group, Inc. (VSNT), whose shares trade on Nasdaq. Versantâs holdings include CNBC, MS NOW (formerly MSNBC), USA Network, Golf Channel, E!, SYFY, Oxygen, and digital properties such as Fandango, Rotten Tomatoes, and SportsEngine.
In June 2026, Comcast said it planned to separate its media businesses from its broadband and telecommunications businesses into two publicly traded companies, subject to regulatory and other approvals. Under the proposal, Cavanagh would become CEO of NBCUniversal and former Comcast Chief Financial Officer Michael Angelakis would become CEO of Comcast.
