As they say (wait, who says?), if you’re gonna go out, go out in style. With the London Olympics now in the books, so obviously are McCann’s marketing duties for the Games (they’ll still be working on the Paralympics, though).  If you didn’t know, the Worldgroup won the responsibilities of official marketing services agency for the 2012 London Olympics and Paralympics back in May 2009. As a result, the agency network, led by McCann London, was tasked with all advertising (tv, press, radio, outdoor, online and mobile), direct marketing and digital marketing and also helped shape the overall look and feel of the Games in conjunction with LOCOG.

Anyhow, McCann put out this ad today, which proudly proclaims that the agency “just lost a client.” If we had to sum this up in a word, maybe we’ll go with, um, “cute.” Check out larger image after the jump.
