While many touted that 2006 would be the year of the mobile ______ (fill in your mobile buzz word here), it is clear from Chetan Sharma’s bi-annual report on the world mobile data market that data services are a real money maker for the mobile service providers, messaging accounting for largest slice of the pie.
From the true and trusted SMS messaging to new services such as Mobile TV, LBS, and others, different services helped in adding billions to the revenues generated for the year. Japan and Korea remain the envy of the global markets and the countries to study and learn from. The US market has been steadily making strong comeback and is soon going to become the biggest mobile data revenue generating market in the world.
Revenues from mobile data were up in all major regions and for all major carriers with data contributing double digit percentage to overall revenues in most cases.
Chetan is one of the most knowledgeable people in mobile that I know. He has a great ability to set aside hype and present the actual data behind what makes mobile tick. His report is definitely worth a read.

I think you meant “semi-annual”. Bi-annual is once every two years. Semi-annual is twice a year.
Scot, actually bi-annual does mean twice a year.
<blockquote> “Biannual” and “semiannual” both mean “twice a year.” “Biennial” means “every two years.” Because of the possible confusion between “biannual” and “biennial,” use “semiannual” when you want to describe something that occurs twice a year. </blockquote>

I was using the same language that Chetan uses to refer to his report.
