Comcast

Comcast Corporation is an American multinational telecommunications and mass media company. It is headquartered in Philadelphia, Pennsylvania. The company provides video, broadband internet, and voice services to residential and business customers in the United States and operates NBCUniversal, a major content and distribution company. Its consumer services are marketed under the Xfinity brand.

The company traces its origins to 1963, when Ralph J. Roberts, Daniel Aaron, and Julian A. Brodsky founded American Cable Systems in Philadelphia. It adopted the Comcast name in the late 1960s and expanded through acquisitions to become one of the largest cable operators in the United States.

In 2011, Comcast acquired a controlling interest in NBCUniversal from General Electric; the transaction was completed in 2013, bringing NBCUniversal’s film and television properties under Comcast. NBCUniversal includes the NBC and Telemundo networks, the Universal Pictures film studio, cable networks, and Universal Parks & Resorts theme parks. Through these assets, Comcast spans content creation, distribution, and theme park entertainment in addition to its traditional telecommunications operations.

Comcast’s business is organized into two main segments: Comcast Cable (home internet, video, and voice services) and NBCUniversal (television networks, film and digital studios, and theme parks). Revenue derives from subscriptions, advertising, licensing, and related activities. The company is publicly traded on the Nasdaq under the ticker CMCSA and is known for its combined emphasis on telecommunications infrastructure and vertically integrated media content.
