We're starting to see a lot of text-based mobile services. While software vendors battle it out to get their programs working on hundreds of possible handsets, text campaigns allow companies to skip all that heartache, since texting works on just about any modern phone.

On the advertising side, 4INFO, a text ad firm that counts GM/Chevy, MobiTV, and Denny's among its client roster, is launching a new SMS text/ad service. The 4INFO Advertising Marketplace lets marketers reach consumers with text ads in tandem with partners USA Today, TV Guide and Spark Networks, as well as 4INFO's own mobile services.

According to 4INFO, text traffic hit 99 billion in 2006 and is expected to reach 142 million by the end of the decade.
