By Wailin Wong | Motorola’s Super Bowl ad starring actress Megan Fox generated a fair amount of online chatter over the weekend, but not as much buzz as Google and Doritos, according to Chicago-based marketing firm Alterian.

Alterian tracked online buzz related to Super Bowl ads between Dec. 1 and Feb. 8, monitoring conversations on forums such as blogs, Twitter and message boards. Heading into Super Bowl weekend, Motorola ranked eighth out of 35 advertisers in volume of mentions. In Alterian’s final results, which saw the total list of advertisers grow to 46, Motorola dropped to 12th in volume. Alterian data showed that the Schaumburg-based was more frequently discussed on Monday than on the day of the game.
