Not to be outdone, fervent Ed fans took out a full-page ad in today's Variety begging NBC to renew the show for a fifth season. "This was above and beyond," says exec producer Rob Burnett of the $5,000 gesture. "We were touched that people would actually spend their own money for something like this." NBC recently told TV Guide Online that Ed's Feb. 6 season finale was likely the show's swan song.
