Although the pitches seen on television last for about ten minutes, they actually last for about one hour. They also must start with 30 seconds of silence to gather a camera shot of the whole set.
Kevin O'Leary was the only Shark to have appeared in every episode, up until the premiere of the ninth season.
When Mark Cuban presents what he believes is a more than fair offer, he gives the entrepreneur twenty four seconds to make a decision or he's out. The twenty four seconds is based on the twenty four second shot clock used in sports where Cuban is the owner of the Dallas Mavericks.
In a single season, as many as 300 entrepreneurs present their product or service but as little as twenty five percent of those presentations are not aired for a variety of reasons.
