The Deutsche Bank AG investor conference in Palm Beach keeps making news… Les Moonves said the broadcast networks may sell fewer ads at the upfront for the 2009-2010 TV season. Sounds a lot like CBS will do what NBC did last year and keep back inventory for the spot market. CBS still expects to raise prices even if marketers do delay spending. “The advertisers are nervous,” Moonves said. “They’re going to be locking their budgets in a lot later.”  Les confirmed that, to cut costs, CBS is producing 6 fewer pilot this year compared with 2008. And he says the network only has room for 3 or 4 new shows in its schedule next season.
