After attempting to reduce the cost of developing new programs in general and avoiding the expensive production costs of pilots in particular, NBC is now planning to spend more than previously on promising projects and says it has 18 pilots in the works compared with 11 before the current season. In an interview with Bloomberg News, Angel Bromstad, president of the network's primetime entertainment unit, said, "We have to take more swings, take more shots creatively, and have more back-up." Bromstad also indicated that until the rest of its programming can be brought up to snuff, NBC will leave Jay Leno in his 10 00 p.m. timeslot. "We have so many holes that we have to essentially rebuild the schedule," Bromstad said in the Bloomberg interview. "Not having the additional five hours has certainly relieved some of the pressure." She also indicated that another show that will definitely return next season is Law & Order , which, she said, is due to become he longest-running primetime dramatic show in TV history. "I'm a Law & Order junkie," she said. "I wouldn't want to be responsible for not having Law & Order break the record." (Launched in 1990, it is currently tied with CBS's Gunsmoke , which ran for 20 years, from 1955-1975. Only The Simpsons has a longer record -- 21 years.)
