Comcast Corporation (NASDAQ: CMCSA) is a diversified global media and technology company headquartered in Philadelphia, Pennsylvania. Its principal operations are organized around Comcast Cable, which provides broadband internet, video, voice and wireless services to residential and business customers in the United States under the Xfinity and Comcast Business brands, and NBCUniversal, a media and entertainment group that develops, produces and distributes content across broadcast and cable networks, film, and streaming platforms.
NBCUniversal's assets include the NBC broadcast network, a portfolio of cable channels, Universal Pictures and other film and television production businesses, and the Peacock streaming service. The company also operates theme parks and resorts through its Universal Parks & Resorts unit. Comcast has expanded its international footprint through acquisitions, most notably taking majority ownership of NBCUniversal in stages and completing the acquisition of Sky, a large European pay-TV and broadband provider, which extends its reach into the U.K., Ireland and continental Europe.
Comcast's service offerings span consumer-facing connectivity and entertainment products as well as advertising, content distribution, and enterprise solutions. In the U.S., Xfinity bundles high-speed internet, video and voice services while offering mobile service through an MVNO arrangement. NBCUniversal and Sky contribute content production, channel distribution, streaming, and advertising capabilities, enabling Comcast to address multiple points of the media and connectivity value chain.
Founded as a cable operator, Comcast has grown through strategic acquisitions and organic investment in network infrastructure and content. The company is led by Brian L. Roberts, who serves as chairman and chief executive officer. Comcast continues to evolve its business model around broadband deployment, direct-to-consumer streaming, content creation and monetization across domestic and international markets.
