LeBron James' prime-time announcement on ESPN that he would be taking his talents to South Beach and the Miami Heat generated $6 million in advertising revenue, according to adage.com, the only arm of Advertising Age magazine. The network donated the time and the ad revenues were donated to various charities. The Boys and Girls Clubs of America were the greatest benefactors, receiving about $2.5 million.

Uber-agent Ari Emanuel is the man behind the program, said adage.com.
