Mark Cuban has said an emotional farewell to "Shark Tank" after 15 seasons on ABC's reality show. The entrepreneur and onetime majority owner of the Dallas Mavericks, 66, gave a special toast to fellow sharks and fans in his final episode May 16 (now streaming on Hulu).

"This show changed me. I think I changed the show, and I think we all together, as sharks, changed America," the billionaire investor says.
