By the end of the third quarter, 34 of the 100 most frequently visited Web sites had put HTML5 to use, said binvisions.com, The Wall Street Journal reported Saturday.
Mozilla Foundation, which produces Firefox, and Opera Software ASA are also including support for HTML5 on their browsers.
The program is noted for being flexible and fast, with venture capitalist Marc Andreessen, one of the creators of Netscape, calling it "a major step forward."
"HTML5 is going to put power back in the hands of creative people," said Roger McNamee, an investor who said the programming would help artists and companies looking for a wider range of Web site options.
Among the advantages to HTML5 is the ability for developers to program applications that can be launched on smartphones, computer tables and computers without having to reinvent the program for each device.
"If you want to be delivering a Web experience around multiple devices, you have to be doing it in HTML5," said Danny Winokur, Adobe's general manager for interactive development.
