NBC Sports chief Dick Ebersol claimed Wednesday that the network has sold all but two of its available commercial slots for the Super Bowl, but Advertising Age said that some media buyers were skeptical and claiming that in order to entice advertisers to buy the time, the network was throwing in, or offering at low cost, ad time on other sports programming, including the pre- and post-Super Bowl shows. The trade publication also listed a number of questions that could help "savvy viewers" in the industry determine just how successful the network had actually been in its sales efforts. Among the questions "How much time does the network devote to promos for its own programs and those of its sister NBC Universal outlets?" And "Are you seeing repeats of the same ad as you watch the game, or do the ads you saw in the Super Bowl turn up during post-game coverage?"
