Spoofing is the sincerest form of flattery. Or at least it would seem so in the world of television. And networks competing against AMC’s “Mad Men” for an Emmy or three were not amused when NBC, which will carry the awards on Aug. 29, released the first in a series of joking “Mad Men”-theme promotional ads this week for the Emmy show. The first ad  in which Jimmy Fallon, wearing a skinny tie, does his best Don Draper, above, with the actress Christina Hendricks as Joan Harris, her character in the series  was broadcast on Wednesday night. But after complaints by other networks, it was pulled from television and the Web, and two more ads have been delayed, according to The Hollywood Reporter. The spots  all featuring Mr. Fallon, who will host the Emmys  will be kept under wraps until after voting for the awards has ended on Tuesday. “Are they kidding?” an unidentified official from one network told the publication. “They’re running basically ads for ‘Mad Men’ in the middle of the voting process. That’s like having a presidential campaign and running an ad for one candidate.” NBC told The Hollywood Reporter that the ads had been released prematurely.
