NEW YORK (AdAge.com) -- Although hyping the advertising potential of HDTV is all the rage across the sales side of televisiondom, more than a few big marketers have yet to be convinced. In fact, one of the biggest, Unilever, is quite unexcited about the whole thing. And that's no small issue, given that the package goods giant buys $2.2 billion worth of U.S. advertising each year. In other news, ABC's sales chief is not happy with talk about programming commercials according to their performance. And some big rock stars have launched their own lines of coffee, which we put to the taste test.
