NEW YORK (AP) -- With Super Bowl Sunday less than a week away, a flurry of advertisers including Budweiser and LG Electronics have already released their game-day ads in the hopes of stoking excitement and building up shares on social media.
Because ads cost up to $5 million per 30 seconds, advertisers are looking to extend buzz to make their investment pay off.
"More than ever we're seeing very elaborate pre-game efforts to generate interest," said Tim Calkins, a marketing professor at Northwestern's Kellogg School of Management.
Here's a look at 10 spots that advertisers have released ahead of Sunday's game on CBS:
