A judge has ordered the billionaire media entreprenuer Alki David to stop calling his new online TV service BarryDriller.com, ruling that the name is misleadingly similar to that of another much bigger media mogul, Barry Diller.

In a 20-page order issued on Wednesday, U.S. District Judge Audrey Collins in Los Angeles enjoined David and several companies affiliated with him from using the terms “BarryDriller.com” and “Barry Driller” (that’s Driller, with an “r”). David launched an online television service by that name in August. According to Diller, who immediately sued, BarryDriller.com is an obvious attempt to capitalize on the early success of Diller’s new online TV start-up, Aereo Inc.
