Opera plans to add capabilities such as Canvas and video to its browser, says Molly Holzschlag, Opera's Web evangelist. Meanwhile, Apple supports HTML 5 audio and video tags in its Safari browser, as well as the Canvas technology (which it invented).
The case for HTML 5: Get rid of proprietary add-ons While Adobe, Microsoft, and Sun Microsystems (soon to be Oracle) duke it out with their own technologies to implement multimedia on the Web, HTML 5 has the potential to eat these vendors' lunches, offering Web experiences based on an industry standard.
Therefore, Adobe Flash and Microsoft Silverlight could see their turf invaded by HTML 5, Almaer says. "Essentially, what it does is lays the groundwork to have equivalent functionality that Flash or Silverlight provides," says RedMonk analyst Michael Cote. It also could threaten JavaFX, he adds.
One of HTML 5's goals is to move the Web away from proprietary technologies such as Flash, Silverlight, and JavaFX, says Ian Hickson, co-editor of the HTML 5 specification. (Hickson is a Google employee, while his co-editor David Hyatt works for Apple.)
"They're single-vendor solutions [and] they don't really fit well into the Web platform," Hickson says. "It's always a problem when you're stuck with a single software provider -- what if they decide to abandon the product you're using? What if they decide to start charging? With an open platform, there's no such risk, since we have true competition, many vendors, and an open standard that anyone can implement."
Hickson adds, "It would be a terrible step backward if humanity's major development platform [the Web] was controlled by a single vendor the way that previous platforms such as Windows have been."
Mozilla wants the Web to stay open and ensure that capabilities such as video are not beholden to corporate entities, says Firefox lead Vukicevic. But whether HTML 5 and Canvas displace Flash, Silverlight, and JavaFX "really depends on what developers do," he adds.
Lack of support for some HTML 5 technologies in the popular Internet Explorer is an issue for developers, says Vukicevic. "The fact that IE doesn't support a lot of these advanced features really holds back Web apps," because developers must instead do extra work such as supporting Microsoft-specific APIs or writing a portion of their application in Flash, he says.
The case for proprietary add-ons: They're better and available today Although all three companies are involved with the W3C's HTML 5 efforts, Microsoft, Adobe, and Sun each defend the need for their technologies.
"HTML 5 is still a standard in progress and the makers of it say it will be five to ten years at least before it's done, so it's too early to make any comparisons at this time," a Microsoft spokesperson says. "Silverlight will still be necessary as it provides more advanced features -- such as a richer and faster programming model (C#), 3-D, and out-of-browser capabilities. With those features, Silverlight will ultimately provide a richer Internet experience."
