The global messaging market continues to be important to mobile carriers, with the bulk of the revenues continuing to come from Short Message Service (SMS) text messaging, reports In-Stat. The greatest growth in mobile messaging, however, will come from wireless instant messaging, which are driven by corporate users and are expected to increase revenues six-fold between 2007 and 2009. In-Stat's study found also found that Multimedia Message Service (MMS), which delivers pictures, sound clips and video, is expected to show nearly 50 percent compound annual growth rate through 2009. The major barrier to widespread consumer adoption of wireless instant messaging will be development of industry standards. Enhanced Message Service (EMS) has virtually disappeared as a viable technology.
