Comcast

Comcast Corporation (simply known as Comcast, and formerly known as American Cable Systems and Comcast Holdings, stylized in all caps as COMCAST), incorporated and headquartered in Philadelphia, is the largest American multinational telecommunications and media conglomerate. The corporation is the second-largest broadcasting and cable television company in the world by revenue (behind AT&T). It is the third-largest pay-TV company, the second-largest cable TV company by subscribers, and the largest home Internet service provider in the United States. Comcast is additionally the nation's third-largest home telephone service provider. It provides services to U.S. residential and commercial customers in 40 states and the District of Columbia. As the owner of the international media company NBCUniversal since 2011, Comcast is also a high-volume producer of feature films for theatrical exhibition and television programming, and a theme park operator.

Comcast owns and operates the Xfinity residential cable communications business segment and division; Comcast Business, a commercial services provider; and Xfinity Mobile, an MVNO of Verizon. Through NBCUniversal, it also owns and operates over-the-air national broadcast network channels such as NBC, Telemundo, TeleXitos, and Cozi TV; multiple cable-only channels such as MSNBC, CNBC, USA Network, Syfy, Oxygen, Bravo, and E!; the film studio Universal Pictures; the VOD streaming service Peacock; animation studios DreamWorks Animation, Illumination, and Universal Animation Studios; and Universal Destinations & Experiences. It also has significant holdings in digital distribution, such as thePlatform, which it acquired in 2006; and ad-tech company FreeWheel, which it acquired in 2014. Since October 2018, it has also been the parent company of Sky Group.

Comcast has been criticized and put under intense public scrutiny for a variety of reasons. Its customer satisfaction ratings were among the lowest in the cable industry during the years 2008–2010. It has violated net neutrality practices in the past, and, despite its commitment to a narrow definition of net neutrality, critics advocate a definition that precludes any distinction between Comcast's private network services and the rest of the Internet. Critics also point out a lack of competition in the vast majority of Comcast's service areas; in particular, the limited competition among cable providers. Given its negotiating power as a large ISP, some suspect that it could leverage paid peering agreements to unfairly influence end-user connection speeds. Its ownership of both content production (in NBCUniversal) and distribution (as an ISP) has raised antitrust concerns. These issues and others led to Comcast being dubbed "The Worst Company in America" by The Consumerist in 2010 and 2014.
