In its 23rd year on TV, “The Simpsons” could be on the endangered species list. The show's producer said Tuesday the show can't continue under its current financial model, following a report that big pay cuts are being sought for the actors who provide voices for Homer, Marge and Bart Simpson and other characters. “We believe this brilliant series can and should continue, but we cannot produce future seasons under its current financial model,” said Chris Alexander, spokesman for 20th Century Fox Television. He said producers hope a deal can be reached. The animated series is a fixture on Fox's Sunday night schedule, and critics consider it one of the best shows in the medium. But like many programs that have been on the air for a long time, the cost of making it has become prohibitive. The Fox network reportedly loses money each year on new episodes.
