By winning his 19th Olympic medal yesterday, Michael Phelps didn't just secure the title of "History's Greatest Olympian." He also earned an honor everyone on Earth has always wished for: A personal message of congratulations in the voice of Morgan Freeman. Visa's quick-turnaround spot, part of TBWA\Chiat\Day's real-time campaign for the global sponsor, aired on NBC after midnight last night. It includes footage from the performance that landed the record-breaking medal, as well as clips of fans cheering from home, collected through a promotion on the brand's Facebook page. Yes, such rapid-response advertising is a bit of marketing gimmickry (one also used four years ago to honor the same guy). But it's also a well-deserved sentiment. So yeah, congratulations, Michael.
