Omaha investor Warren Buffett's Berkshire Hathaway Corp. has named Comcast Cable Communications president Stephen B. Burke as its newest director, Berkshire says here.

On the Berkshire board, Burke will serve alongside Thomas Murphy, who used to run Capital Cities/ABC with Burke's father, Daniel, when Buffett was a major investor in the company; also Microsoft Chairman Bill Gates; Allen & Co. boss Donald Keough; and others listed here.

Burke, 51, who joined Comcast in 1998 from Disney, is also a member of JPMorgan Chase & Co.'s board, where his peers include: William C. Weldon, head of Johnson & Johnson, where Burke's uncle James E. Burke was once chief executive; Philadelphia congressman-turned-Washington lobbyist Bill Gray, whose clients include Comcast; and others listed here.

Burke's power in US media is expected to grow with Comcast's planned takeover of NBC Universal. Besides his corporate posts, he's also served as trustee chairman of the Children's Hospital of Philadelphia.
