Justin Long, who plays Mac in the Get a Mac ads, has told The Onion's A.V. Club that he believes the Get a Mac ad campaign has come to an end. When The Onion asked Justin what the status was on the Apple ads, he replied, "You know, I think they might be done. In fact, I heard from John, I think they're going to move on. I can't say definitively, which is sad, because not only am I going to miss doing them, but also working with John."
The Get a Mac ads have been widely applauded by the advertising industry, winning a Grand Effie Award in 2007. The campaign was first launched in the US in 2006, and Apple then expanded it to Canada, the United Kingdom, Australia, New Zealand, and Japan. The US and Canadian ads starred Justin Long as Mac and John Hodgman as PC. The two have appeared together in 66 television ads to date. The pair has also featured in 10 Web-only ads posted on various Web sites like The New York Times.
Apple has gone spans of time with no TV advertising for their Mac computers before. It's possible that they will be throwing all their ad dollars behind the iPhone and iPad for the time being. However, if Justin Long is correct that the Get a Mac ads are over, it does not preclude that a new Mac ad campaign is in the works.
