Shark Tank is produced by Mark Burnett and based on the format Dragons' Den, which originated in 2001 with the Japanese show Tigers of Money. Shark Tank, however, more closely resembles the format of the British version of Dragons' Den, which premiered in 2005. The show features a panel of potential investors, called "sharks", who consider offers from aspiring entrepreneurs seeking investments for their business or product. The sharks are paid for their participation in the show, but the money they invest is their own. The entrepreneur can make a deal on the show if a panel member is interested. However, if all of the panel members opt out, the entrepreneur leaves empty-handed. The show is said to portray "the drama of pitch meetings and the interaction between the entrepreneurs and tycoons. " A one-hour pitch by a contestant is edited down to "a dramatic 10-minute segment. "
