Shark Tank is produced by Mark Burnett and based on the TV show Dragon's Den. The show features a panel of potential investors, called "sharks", who consider offers from aspiring entrepreneurs seeking investments for their business or product. 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(Shark Tank) 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". The Shark Tank show is said to personalize "the desperation and pain experienced by victims of a broken down economy". The "sharks" often find weaknesses and faults in an entrepreneur's concept, product, or business model. Some of the investors try to soften the impact of rejection, like panel member Corcoran, while others such as O'Leary can be "brutal" and show "no patience even for tales of hardship". Many deals made on the show are never enacted due to the investor's vetting process following the deal, which includes product testing and the examination of the contestants' personal and business financials. The show initially required each contestant to sign an agreement with Finnmax, the producer of Shark Tank, promising Finnmax the option of taking a "2 percent royalty" or "5% equity stake" in the contestant's business venture. However, in October 2013, this requirement was repealed by the network, retroactively, due to pressure from panel member Mark Cuban.
