Liberty Global may call the US home, but most of its cable TV subscribers watch its channels in Europe. The company provides cable programming and content distribution, digital telephone service, and broadband Internet access through a number of operating subsidiaries. Its core market is western Europe, where it does business through UPC; in Germany, through Unitymedia; in Switzerland, through Cablecom, and in Belgium, through a controlling stake in Telenet Holding. The company also owns 55% of Australia's AUSTAR, 80% of Chile's VTR, Liberty Cablevision in Puerto Rico, and offers satellite TV in select European markets. Chairman John C. Malone controls almost 39% of the company's voting power.
