An article from Media Post explains how The Wireless Advertising Association (WAA) plans on setting standards for wireless advertising.
The WAA issued its first creative standards for advertising messages sent via SMS over GSM networks. First, a “Full Message” is an ad type that consists of the full 160 characters available in an SMS. Second, “Sponsorship” is standardized as 34 characters, which are two lines of text on most phones. This format is designed for sponsoring content that occupies the rest of the message.
