AT&T Wireless, which claims to have taught US how to text with its “American Idol” campaign, and McDonald’s are starting this week an on-packaging SMS text messaging campaign to promote the Olympic Games in Athens.

The fastfood company will distribute Olympic-related trivia games on more than 250 million to-go bags. Only AT&T Wireless subscribers will be able to test their Olympic knowledge by using the text messaging feature on their wireless phones to answer the questions.
