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

In a 20-page order issued 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”). The site was down Thursday.
