Jay Leno

Today NBC launches Jay Leno's new hour-long primetime show at 10 pm as part of a plan for the network to bring down costs and take a different approach to its primetime lineup.

Now, instead of competiting with the dramas on ABC and CBS, as well as the increasingly-successful programming on cable channels like USA, NBC is providing a comedic alternative, hosted by the most popular name in Late Night television. Though Leno's show may cost just a fraction the cost of a traditional primetime drama, NBC isn't saving any on its promotion of the show: NBC's been promoting tonight's debut since the Super Bowl in Feruary and the marketing budget is estimated at more than $10 million.
