NEW YORK Less than 48 hours after the big game, the buzz around many of the top commercials has died down, yet the staying power of free food remains.
 
Denny's, which closed its spot on Sunday with an offer to buy America a free breakfast this morning, has seen a huge spike in Twitter conversations about the brand, according to Trendrr, an analysis service. Discussion of the restaurant chain topped 1,700 mentions today on the short-messaging service, compared to an average of 59.
 
According to Twitter's search service, Denny's is one of its top trending topics today.



In comparison, Trendrr found a steep drop in chatter about Doritos, winner of the USA Today poll for best Super Bowl spot. Doritos peaked at nearly 3,300 mentions yesterday, but then fell to 933 today.

Similarly, Pepsi and Coke saw big jumps in references -- 373 percent for Coke Zero and 244 percent for Pepsi -- that also proved temporary. Like fellow Super Bowl advertisers Gatorade, Audi and Hyundai, chatter quickly fell today to its pre-Super Bowl level.
 
Some Super Bowl advertisers saw only modest increases: Cars.com's Twitter chatter increased 14 percent and Monster gained 29 percent, per Trendrr.
 
Twitter saw an explosion of chatter around the Super Bowl advertising, as chronicled by different hashtag users adding their messages to group updates about a particular subject.
