The iPad now accounts for 97.2 per cent of all tablet internet traffic in the US in August 2011, according to a report from market research company comScore.
The report - called "Digital Omnivores: How Tablets, Smartphones and Connected Devices are Changing US Digital Media Consumption Habits" - illustrates the degree to which Apple's tablet has come to dominate the American market.
It has even surpassed the iPhone in terms of internet traffic on iOS devices: 46.8 per cent versus the iPhone's 42.6 per cent.
And iOS devices account for the largest share of mobile internet traffic overall, measured in browser-based page views. By this metric, iOS accounted for 58.5 per cent of US non-computer traffic in August, followed by Android with 31.9 per cent.
The volume of iOS traffic relative to Android is particularly striking when compared to their respective market shares: in terms of devices in use, Android is the most popular OS, with 43.7 per cent of the smartphone market in August; iOS had 43.1 per cent.
"The popularisation of smartphones and the introduction of tablets and other web-enabled devices...have contributed to an explosion in digital media consumption," said comScore's senior vice president of mobile Mark Donovan.
"As these devices gain adoption, we have also seen the rise of the 'digital omnivores' - consumers who access content through several touchpoints during the course of their daily digital lives."
"In order to meet the needs of these consumers, advertisers and publishers must learn to navigate this new landscape so they develop cross-platform strategies to effectively engage their audiences."
