I’m told that General Electric, parent company of NBC, held its corporate inauguration party today from 11 AM to 1 PM in Washington D.C. Attending were GE CEO Jeff Immelt, NBC Universal boss Jeff Zucker, Universal Studios mogul Ron Meyer, and bunches of other company bigwigs from the far less glamorous divisions. My sources say Ben Silverman, the co-chairman of NBC Entertainment and NBC Universal Television, was supposed to be there but was glaringly absent. One showbiz PR type says he saw Ben last night around 6 PM in Sundance at Village At The Yard. But at the GE party, Immelt was overhead asking Zucker, “Did your boy show?” To which Zucker responded, “No.” …”Classic Ben,” one source told me. Uh-oh, is Silverman starting to miss important appointments yet again? But I’d love to give him the benefit of the doubt that he may have snuck into the party late…
