Liberty Media founder John Malone, who is nicknamed ‘the king of cable’ by the US media, controlled Tele-Communications Inc (TCI), which he grew into the largest cable operator in the United States. After a failed merger attempt with Bell Atlantic in 1994, TCI was purchased by AT&T Inc in 1999, and the cable television assets were later acquired by both Charter and the Comcast Corporation.
