When was the halftime limit established?

Before the 2017 season, the National Football Foundation set the limit for a college football halftime at 20 minutes. Schools may make halftime shorter, but they can't make it longer. 

“The hope is that these steps will halt the trend for longer game times,” a National Football Foundation official said.
