The phone shipped on June 21, but didn't reach the shelves of all five of its U.S. carriers until July 12. Those carriers are AT&T, Sprint, T-Mobile USA, Verizon Wireless and U.S. Cellular.
Chitika measures Web usage by the number of users seeing ads on Web pages and based its Galaxy S III study on hundreds of millions of ad impressions.
The quick upsurge in Web traffic for the S III put it ahead of the Galaxy Nexus by Aug. 5, but behind the Galaxy S and Galaxy S II.
Chitika said all Samsung mobile Web traffic still lags "far behind" the , with only 0.24 impressions per one iPhone impression. But Chitika added that Samsung's "suite of phones remain the iPhone's closest challenger for the top spot."
Chitika, however, questioned whether the S III would have staying power once the faster, bigger iPhone 5 is released in September.
