In its quest to make its Silverlight technology as ubiquitous as its competitor Flash, Microsoft is moving full speed ahead to promote adoption of the technology through some strategic moves and partnerships it will highlight at its annual MIX 08 conference, including a deal with Nokia to put the technology on mobile devices.

Through a deal it will reveal Tuesday, Microsoft is working with mobile handset provider Nokia to put Silverlight on wireless devices for the first time, said Tom Honeybone, senior director in Microsoft's developer division. Silverlight is a cross-platform plug-in that lets developers create multimedia and Rich Internet Applications (RIA) and then run them from the browser.

At MIX, Nokia plans to reveal a beta program for its runtime for Silverlight on its Series 60 and Series 40 handsets, as well as demonstrate Silverlight applications running on the handsets, he said. By year-end, Nokia plans to ship handsets with the runtime embedded that can run Silverlight applications, beginning first with the high-end Series 60 smartphones, Honeybone said. Silverlight on Series 40 phones and on Nokia's tablet devices will be available thereafter.

Microsoft eventually plans to include a runtime for Silverlight in its Windows Mobile platform, but it chose Nokia as the first company to bring Silverlight to handsets because of that company's prominent position in the mobile handset market, Honeybone said. "Series 60 is the clear leader, " he said. Nokia is not currently one of Microsoft's Windows Mobile handset partners, though there have been rumors that the company eventually will sign on to build Windows Mobile devices alongside competitors such as Sony Ericsson and HTC.

Microsoft will be developing a portability kit so Nokia can port Silverlight from the desktop to its mobile platform; that kit eventually will be available to other handset providers as well, Honeybone said.

Microsoft released Silverlight 1.0 in September 2007 as a plug-in for browsers that could work on Windows, Linux and the Mac platform. Microsoft developed the technology to displace Adobe's Flash, which currently has about 97% to 99% penetration on the Web as a technology for delivering multimedia content and RIAs.

Flash also is available on wireless devices as Flash Lite; the technology is available on more than 450 million phones, according to Adobe.
