The U.S. mobile data market ballooned to $14 billion in the third quarter, up 25 percent from the year-ago period, according to a new report from analyst Chetan Sharma. Verizon Wireless (NYSE:VZ) and AT&T Mobility (NYSE:T) together accounted for 85 percent of mobile data revenue growth in the third quarter, Sharma said. Further, the report said data traffic will continue to rise, and that by the end of 2010 average U.S. data consumption will be around 325 MB per month, up 112 percent from 2009. Sharma's report contrasts sharply with a separate one from Analysys Mason, which said that measured mobile data traffic growth in Europe is not doubling every year, as some have claimed. The report said that while European mobile data traffic grew by 110 percent in 2009, it will grow by about 35 percent in 2010--and that there is no real prospect of a pick-up in growth rates in 2011. Sharma's report said that total U.S. mobile data traffic will exceed 1 Exabyte for the first time by the end of 2010. Article
