The introduction of Windows 10 was another contributor to IE's fall, as the new operating system demoted IE to a legacy role and promoted Edge as the replacement. But Windows 10 users, who now make up nearly 20% of all PC owners, have been hesitant, increasingly so, to adopt Edge: In May, fewer than three in every 10 Windows 10 users chose Edge. That number has been slowly declining -- it was two out of three in October -- since Windows 10's launch last year.
Other data sources mirrored Net Applications' data, and also showed a decline -- albeit less dramatic -- for IE + Edge. The Digital Analytics Program (DAP), which counts visits to more than 4,000 websites operated by the U.S. government, indicated a drop of 1.2 percentage points, to 20.2%, for Microsoft's browsers in May, and an increase of four-tenths of a point, to 43.9%, for Chrome.
DAP's traffic is predominantly domestic, although at times as much as 15% of the visitors access the sites from overseas. Data from DAP differs from Net Applications' because the former includes smartphone-based browsers, including Chrome on Android and Safari on iOS, which the latter does not.
After Microsoft mandated that Windows customers upgrade their browser, IE steadily ceded momentum to Google's Chrome, which became the top dog in April and extended its lead in May. Data: Net Applications. (Click for larger image).
