The San Diego Chargers have a year to decide if they want to join the Rams in a proposed stadium in Inglewood, CA, the site of the old Hollywood Park racetrack, which is about 10 miles from Downtown LA.
If the Chargers don't follow, the option falls to the Oakland Raiders.
Originally, Rams owner Stan Kroenke proposed a plan to move to Inglewood that was competing with a joint proposal from the Chargers and the Raiders to share a stadium in Carson, CA.
After neither scenario received the required 24 of 32 votes from owners, compromises started being made, until 30 of the 32 teams agreed to house the Rams in Los Angeles with the possibility of being joined by another team.
The Inglewood stadium isn't expected to be ready until 2019. The Los Angeles Coliseum has been cited as a possible temporary arena until then, but at the moment it is only permitted to host one professional team at a time. That rule may be changed, or the Chargers may have to look for another transitory home if they don't remain in San Diego.
The Rams resided in Los Angeles from 1946 until 1995, when they moved to St. Louis.
"Today, with the NFL returning home, Los Angeles cements itself as the epicenter of the sports world," Los Angeles Mayor Eric Garcetti said after the decision. "We cannot wait to welcome the Rams, and perhaps others soon, as they join a storied lineup of professional franchises, collegiate powerhouses and sports media companies."
Citizens of St. Louis, who also lost an NFL team in 1988, weren't so pleased.
"It is troubling that the league would allow for the relocation of a team when a home market has worked in good faith and presented a strong and viable proposal," said Missouri governor Jay Nixon. He called the league's approval "a clear deviation from the NFL's guidelines."
Maybe some Twitter reactions will cheer St. Louis fans up.
