Les stats AdMob ne confirment pas un éventuel ralentissement au niveau mondial, vous tirez des conclusions générales à partir du seul marché canadien.

Le ralentissement des ventes au Canada semble imputable à l’opérateur Rogers dont les tarifs sont prohibitifs. L’arrêt de leur offre spéciale à la fin du 3ème trimestre, consentie pour apaiser les consommateurs, a provoqué une chute des ventes au 4ème trimestre.

“Another likely reason Rogers’ iPhone sales fell so precipitously is because the notoriously parsimonious wireless carrier stopped offering its most affordable data package at the end of the third quarter.

When Rogers initially announced iPhone plan details in June of 2008, tens of thousands of Canadian consumers were enraged by the carrier’s prices and lack of an unlimited data plan, which is one of the most heavily promoted selling points of Apple’s revolutionary handset in nearly every market where it is available. They responded by signing an online petition—more than 57,000 people—demanding a change in policy.

Within weeks, Canada’s largest wireless carrier relented in part by offering a time-limited $30 data-only add-on (6GB). That “deal” was originally scheduled to end on Aug. 31, but the company extended it until Sept. 30.”
