In the set-top arena, Scientific-Atlanta once enjoyed 100% market share with Time Warner Cable, Cablevision and AT&T U-verse; all three companies have since started to transition to other boxes, Cablevision using Samsung, while TWC and U-verse are split between SA/Cisco and competitor Arris (formerly Motorola). Comcast also has a split account with the two companies. Other companies that have split accounts with SA and Arris are Suddenlink Communications, Charter Communications and Cox; the two vendors also had split accounts for Adelphia before that company went under in 2006. Pace plc, who mainly competes in foreign markets, serves as a domestic rival, but on a limited scale.
