Apple’s (AAPL) success is attributable to a number of things, and the $1 billion the company spends annually promoting its wares certainly plays a significant role. Its most recent round of Mac commercials was universally panned, however, with one widely respected industry executive going as far as to say the public’s “gagging response” to the ads was well deserved. The ads were pulled after their first week on air during the Olympics and now Advertising Age reports that Scott Trattner, the executive creative director behind the commercials, has left his job at TBWA/Media Arts Lab and moved to a new agency. Trattner would not confirm that the Genius ads had anything to do with his departure from TBWA.
