entrepreneurs who agree to be on 'the shark tank' are asked to sign a contract that would give the producer (mark burnett) 2% of net revenues - in perpetuity! this is a complete joke. first, no entrepreneur with a decent idea that's remotely scalable would ever agree to such terms . . . and second, no investor would ever put money into such an encumbered enterprise.
so they're setting up for failure: the only entrepreneurs who would ever agree to such a preposterous structure would be desperate losers - and who wants to watch them?
incidentally, contestants on 'dragons den' did not have to give the producer anything.
