Magic Johnson

Earvin “Magic” Johnson may have retired from professional sports over 20 years ago, but he’s never left the spotlight. He heads Magic Johnson Enterprises, a multimillion-dollar company with subsidiaries in the entertainment industry. In 2012, he joined an ownership group that bought the Los Angeles Dodgers from former owner Frank McCourt for $2 billion.

In 2011, Johnson teamed up with Detroit Venture Partners, a venture capital firm that backs “seed and early-stage technology companies who have a purpose.” One such tech company is Sociocast, which helps companies target advertising on the web and on mobile devices.
