MARK CUBAN, BARBARA CORCORAN, KEVIN O‚ÄôLEARY, LORI GREINER, ROBERT HERJAVECMore unscripted renewals at ABC. Getting a sixth-season pickup is MVP Shark Tank, which has been driving ABC’s demo ratings dominance on Friday and which has stepped in to fill any hole the network might have open with its well-performing repeats. Sony TV is producing. The Bachelor, from Warner Horizon, has been picked up for a 19th cycle after a controversial but well-rated season with bachelor Juan Pablo Galavis. And the oldest of them all, America’s Funniest Home Videos, has been renewed for a 25th (!), which longtime host Tom Bergeron said would be his last.
