In 2001, Comcast announced it would acquire the assets of the largest cable television operator at the time, AT&T Broadband, for US$44.5 billion. The proposed name for the merged company was "AT&T Comcast", but the companies ultimately decided to keep only the Comcast name. In 2002, Comcast acquired all assets of AT&T Broadband, thus making Comcast the largest cable television company in the United States with over 22 million subscribers. This also spurred the start of Comcast Advertising Sales (using AT&T's groundwork) which would later be renamed Comcast Spotlight. As part of this acquisition, Comcast also acquired the National Digital Television Center in Centennial, Colorado as a wholly owned subsidiary, which is today known as the Comcast Media Center.
