So far, marketers have used text messaging in various ways ranging from conveying basic information to rewards programming to couponing, according to Nielsen.
Among high-profile campaigns, the measurement firm pointed to Coca-Cola's "My Coke Rewards" program, which 1.1 million AT&T and Verizon Wireless customers participated in during the third quarter. Subway, Arby's, Jiffy Lube, BestBuy, and other major brands have also run text campaigns.--Mark Walsh
