While most media companies, fearing copyright suits, discourage the general public from submitting unsolicited scripts and program ideas -- and indeed usually return such submissions or discard them -- Mark Cuban, the owner of HDNet, said on his website Monday that "one of the fun things" he does at the channel is reading ideas for new shows. Cuban, who also owns the Dallas Mavericks basketball team, gives this advice to anyone wanting to submit an idea to him: "I don't need to be pitched another cooking, poker, pimp my whatever, American Idol knockoff, nor do I want to hear another 'compete for a Mavs roster spot' or 'business plan competition idea.' What I would like to read are original show ideas. So post them if you got them."
