Every year my former colleagues at USA TODAY use technology to try to figure out which was the most popular Super Bowl ad.

Using handheld meters, adult volunteers register their reactions as each ad is broadcast. This year's top-rated spot: The "Betty White" ad from Snickers.

Over at FoxNews.com, there's an unscientific survey and it's producing a much different result. The "winner" there: Focus on the Family's "Tim Tebow" ad, which sparked some controversy because it's an "advocacy" ad (in this case, a subtle "pro-life" message).

The Tebow ad scored quite low in USA TODAY's rankings.

Of course, online surveys can be skewed by concerted efforts to affect the results (as appears to be happening right now to a question we asked earlier today). Which is why we always try to remember, when we ask such questions, to remind Two-Way readers that they aren't "scientific" surveys. Instead, they're conversation starters.

Update at 11:20 a.m. ET: "Gabe" at Videogum says the best ad on TV yesterday didn't air on CBS during the Super Bowl. Rather, he likes this Subaru spot that was on during Animal Planet's Puppy Bowl VI. Being a dog person, I have to say I also like it a lot too:

Our blogging cousin Linda Holmes over at Monkey See liked Google's ad the most.
