'Shark Tank' to return -- for one episode

Mark Burnett's "Shark Tank" will return to ABC this summer -- for one episode. The airing is a holdover from last season. The well-regarded, if ratings challenged, reality effort will air Thursday, July 15, at 8 p.m., with "Shark" repeats airing in the following weeks. 

ABC still has some time before the deadline to decide on a second season; producers have pitched shaking up the panel of sharks by adding a high-profile name or two. So far, however, there's still no official verdict on "Shark Tank" -- or ABC's other altruistic reality effort, "Jamie Oliver's Food Revolution."
