Torrey Smith of the Baltimore Ravens celebrates with the Ravens cheerleaders after winning Super Bowl XLVII.

Chevrolet will be back in the lineup when the teams take to the field in Super Bowl XLVIII, reversing a controversial 2012 decision to pull out of what is television's most watched annual event—and a program that millions of Americans watch as much for the commercials as for the football.

The decision is the latest reversal of a series of widely debated decisions made by General Motors' former global marketing director, Joel Ewanick, before his departure in July 2012. GM has also decided to test out new opportunities on Facebook, another marketing outlet that Ewanick rejected before he was himself ousted because of a controversy involving costly marketing ties to European soccer.
