During the actual game, I missed the first part of the NFL's ad thanking their fans during Super Bowl XLIV (2010), but thanks to the magic of YouTube, I've had a chance to watch it over and over.
The next ad could apply toward several corporations and government entities near you as well.
Super Bowl 2006 | CareerBuilder
Super Bowl 1977 | Xerox Monk Ad
Super Bowl 2009 | Hulu Ad
Super Bowl 2005 | GoDaddy Ad
While GoDaddy has taken controversial Super Bowl ads to the edge, if you want to register a name (cheaper than GoDaddy), check out SuperstarNames.com, where every internet domain name benefits charity (currently the American Red Cross efforts in Haiti).
