T-Mobile is one of first advertisers to run a 1-minute video ad.
BarnesandNoble.com came in second.
Blockbuster’s mobile site produced the fastest iPhone access time across all service providers among large web retailers in June, says Compuware Gomez. Last month, Blockbuster.com produced an average iPhone mobile response time of 4.75 seconds.
BarnesandNoble.com came in second for iPhone testing with 5.06 seconds, followed by Williams-Sonoma.com (5.10 seconds), Rakuten.com (5.15) and OfficeDepot.com (5.94).
Gomez measures the average iPhone response time for the three major service carriers: AT&T, Sprint and Verizon. Testing for each all 20 retailers takes place once per hour per carrier from two U.S. locations (Virginia and California).
Gomez measures response time as the end-to-end time elapsed while downloading each mobile site.
