When does Shark Tank return?

The show is the American franchise of the international format Dragons' Den, a British TV series, which itself is a remake of the Japanese TV show The Tigers of Money. The show features a panel of investors called "Sharks," who decide whether to invest in their companies. The sharks are paid as cast stars of the show, but a disclaimer at the start of each episode states the money they invest is their own. The series has been a ratings success in its time slot.
