Each year has seen a new flagship smartphone from rivals Apple and Samsung, and one research firm studied the adoption rate of two of their devices.

Chitika Insights acknowledged Apple and Samsung have been engaged in a "bitter rivalry" in both the North American and worldwide marketplace. While the two companies are expected to launch flagship devices such as the Samsung Galaxy S5 and the Apple iPhone 6, Chitika Insights decided to study the initial adoption rates of the Galaxy S4 and iPhone 5 following their respective launches across Canada and the United States.

According to Chitika Insights, in the report "North American Usage and Adoption Comparison: Apple and Samsung," "tens of millions" of Canadian and U.S. Apple and Samsung smartphone-based online advertisement impressions were examined through the Chitika Ad Network.

The ad impressions collected for the study were gathered during the first, fifth, and ninth weeks of the iPhone 5's and Galaxy S4's launch, which were Sept. 21 2012, and April 26, 2013, respectively.

The report revealed adoption of the iPhone 5 "outperformed" the Galaxy S4 during the first two months following each smartphone's individual market debuts. One week into the iPhone 5's release, the fifth-generation smartphone generated nearly 4 percent of overall iPhone traffic in Canada and U.S.

The Galaxy S4 took longer to encounter growth. Its highest growth occurred between the fifth and ninth week following its release date. By the ninth week, the iPhone 5 accounted for 11 percent of iPhone web traffic while the Galaxy S4 held single digits at 6 percent.

Although Samsung could not topple Apple in smartphone adoption, the Galaxy S4 did provide the Google Android mobile operating system with a boost. Samsung clearly drives the most Android-based Web traffic, but Apple products generally outperform in the market share, regardless if it's smartphones or tablets. By the end of January 2014, Samsung accounted for 54 percent of the Android-based Web traffic while other devices with the same mobile platform collectively held at 46 percent.

The methodology for the study was based on overall web usage and not unique users.

"This means that if a user views ten pages that contain Chitika code, they will register ten ad impressions," Chitikia noted in its report. "All Chitika ad impressions in this study are generated through Web browsing, not mobile or desktop applications."

According to the research firm, its typical sample for a study is approximately 300 million Canadian and U.S. impressions, once again measured by page views than unique visitors.
