Comcast Corp. took its fight against the sale of the Texas television channel that broadcasts Major League Baseball's Houston Astros and the National Basketball Association's Houston Rockets to the courtroom, Dow Jones Daily Bankruptcy Review reported today. Bankruptcy Judge Marvin Isgur began hearing arguments on Monday over whether Comcast SportsNet Houston can get out of bankruptcy by selling itself to DirecTV and AT&T Inc. Under the proposal, the channel would not repay a roughly $100 million loan that Comcast extended to get the network started in 2012.
