Riot Games was founded in 2006 by Brandon Beck and Marc Merrill with the intent to change the way video games are made and supported for players. In 2009, Riot released its debut title League of Legends to worldwide acclaim. The game has since gone on to become the most played PC game in the world and a key driver of the explosive growth of esports. Players are the foundation of our community and it’s for them we continue to evolve and improve the League of Legends experience. Riot Games is headquartered in Los Angeles, CA and has 23 offices worldwide.
