USA Today has named the latest entry in Windex's ongoing "bird" campaign as the most liked ad of 2006. This one features two birds who clean a patio door so well that a guy walks into it, a comedic device that's been used about 7,403 times just since 2004.

Artistic gripes aside, what's interesting is that according to the USAT's Ad Track survey, just a quarter of the ads screened were liked by more than 21 percent of the audience. That's an incredibly low number. Humor and nostalgia seemed to be the biggest common threads among commercials that worked well. Auto ads did not fair well despite being among the top spending industries out there.
