Whois & Analysis for comcast.com

Comcast Corporation (formerly registered as Comcast Holdings) is an American global telecommunications conglomerate that is the largest broadcasting and cable television company in the world by revenue.

It is the second-largest pay-TV company after AT&T, largest cable TV company and largest home Internet service provider in the United States, and the nation's third-largest home telephone service provider.

Comcast services U.S. residential and commercial customers in 40 states and in the District of Columbia.

The company's headquarters are located in Philadelphia, Pennsylvania.

As the owner of the international media company NBCUniversal since 2011, Comcast is a producer of feature films and television programs intended for theatrical exhibition and over-the-air and cable television broadcast.

Digital cable is any type of cable television distribution using digital video compression for USE.

The technology was originally developed by General Instrument before being acquired by Motorola and subsequently acquired by ARRIS Group.

Cable companies converted to digital systems during the 2000s, around the time that television signals were converted to the digital HDTV format, which was not compatible with earlier analog cable systems.

In addition to providing higher resolution HD video, digital cable systems provide expanded services such as pay-per-view programming, cable internet access and cable telephone services.

Most digital cable signals are encrypted, which reduced the high incidence of cable theft which occurred in analog systems.

Cable television is a system of delivering television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fiber-optic cables.

This contrasts with broadcast television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television.

FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables.

Comcast Cable Communications (DBA Xfinity) is the cable television division of Comcast.

Xfinity's CEO is Dave Watson, its chairman is Brian L.

Roberts, and its CFO is Catherine Avgiris.

Internet access is the process that enables individuals and organisations to connect to the Internet using computer terminals, computers, mobile devices, sometimes via computer networks.
