Levi's Stadium
On May 8, 2013, the 49ers announced that San Francisco-based Levi Strauss & Co. purchased the naming rights to the new stadium. The deal calls for Levi's to pay $220.3 million to the city of Santa Clara and the 49ers over 20 years, with an option to extend the deal for another five years for around $75 million. On September 14, 2015, ESPN's Chris Berman coined the name "The Big Bellbottom" in reference to the stadium. In a Deadspin article covering the 49ers on August 18, 2015, article writer Drew Magary coined the nickname "the Jeanhole" for the stadium.
49ers–Raiders rivalry
The 49ers–Raiders rivalry, more commonly known as the Battle of the Bay, is a professional American football rivalry between the National Football League (NFL)'s San Francisco 49ers and Oakland Raiders. This rivalry is unique in that both teams are members of different conferences within the NFL and have never met in a postseason game, making the rivalry purely geographic, as only 27 miles across San Francisco Bay separate Levi's Stadium, home of the 49ers, and Oakland-Alameda County Coliseum, home of the Raiders. The geographic aspect of the rivalry will end no later than 2020, when the Raiders relocate to Las Vegas, Nevada. Their 2018 Week 9 match up was their last true Battle of the Bay game barring any sudden changes to the NFL's schedule rotation.
