I read an article today that said a tv-dvd only needs to sell 13,000 copies to make a profit. If this is the case, then why are companies like Fox (with Mary Tyler Moore) and Columbia (with Mad About You, Larry Sanders and Jeffersons) so hesitant to release future seasons of certain shows that aren't moving blockbuster numbers? It's insane for Fox to expect Simpson numbers for MTM, but hey, season 1 sold (as reported a month ago) 85,000 copies... therefore it did make a reasonable profit, but since it's not Simpsons, Family Guy or even Mash or Buffy, Fox pretty much killed that off. And Columbia has jerked several shows around, shows you cannot expect to move Seinfeld numbers. But I am sure that Mad About You season 2 or Jeffersons season 2 sold over 13,000 units. A profit is a profit, so why are companies afraid of continuing certain shows on DVD even if they are still making more back then they put into it? Not every show is as well liked as The Simpsons or has a devoted cult following like Buffy The Vampire Slayer. If all you need is 13,000 copies sold to break even, and MTM sold 85,000... what's the holdup? Fox still made their money back on it several times over. If it's making money, but not paying back ten-fold, why give up on it?
