PORTLAND, Ore. ( TheStreet) -- March Madness is a weeks-long wonderland of marketing opportunities for companies who want to connect with college basketball's audience, but how close is it to becoming the biggest game in town?Closer than you think. Last year, the NCAA men's tournament's Final Four brought in $183.8 million in advertising revenue for broadcast partners CBS ( CBS) and Turner Sports, according to Kantar Media. That's a March Madness record and a big part of the reason those broadcasters paid $10 billion for the rights to broadcast the tournament through 2024. It was still well shy of the $262.5 million the 2012 Super Bowl brought in for NBC ( CMCSA), but much better than the $153 million in ad money that the San Francisco Giants' four-game sweep of the Detroit Tigers earned for Fox ( NWS) back in October. It's a big deal for the Final Four, which has been running in third place since 2009 after bringing in just about $9 million less in ad money than the Super Bowl back in 2008. That year, the Super Bowl generated only $186.3 million in ad revenue for Fox, which is about $2 million or so more than the Final Four is making right now. Look at it from a complete postseason perspective, however, and the Final Four is gaining on the NFL's big game a lot more quickly. In 2011, the last year for which Kantar had data available, the entire NCAA Men's Basketball Tournament yielded $738 million in ad money from NCAA sponsors including General Motors ( GM), AT&T ( T), Coca-Cola ( KO), Capital One ( COF), Nissan ( NSANY) and Lowes ( LOW). Other heavy hitters such as Anheuser-Busch InBev ( BUD) and SAB Miller, which can't partner with the NCAA because of its alcohol policy, also contributed nearly $50 million on their own. That total trailed only the $900 million made by the Super Bowl, but pulls more players into the game than the 30 or so parent companies that buy ad time for the NFL's championship matchup. Roughly 80 companies advertise during the tournament each year, though even that number is down from the 125 companies that kicked in for March Madness ad time in pre-recession 2007.
