Samsung's Galaxy S3 smartphone is set to overtake the original Galaxy S in terms of mobile internet traffic, according to analysis by the online advertising agency, Chitika.

The last report published by Chitika Insights showed the Galaxy S III representing 11.23% of all Samsung smartphone web usage through Aug 6th, 2012. With the phone's popularity still growing, Chitika conducted another study examining the hundreds of millions of smartphone impressions during the last two weeks, from August 7th, 2012 to August 20th, 2012.

As seen in the graph below, the Galaxy S III has maintained a steady rate of Web usage growth. In the last two weeks, the phone's usage share grew nearly 26% --- from 12.07% of all Samsung mobile phone traffic to 15.17%.

The newest handset still lags the Galaxy S2 by a wide margin, although the rate of growth suggests it will overtake it by the end of the year.

Chitika suggests that the small bump in Galaxy S II usage (red line) around August 7th is likely due to the significant online price drop for that phone that day.
