Nokia, the world’s leading mobile phone supplier announced that it would lend assistance to Microsoft’s Silverlight Web video technology to millions of its handsets. This news comes after the two giants sign an agreement.

Nokia said Silverlight would first be available for S60 software platform, used in more advanced phones, but afterwards also for S40, which is used in many of Nokia’s cheaper phones.

Nokia’s S60 software platform is extensively used in Nokia’s line-up. It is also being used in advanced cellphones of LG Electronics and Samsung Electronics. Microsoft’s own Windows Mobile is seen to be its closest rival with just over 10 percent of the market.

Silverlight is also a rival to Adobe System Inc’s Flash technology. Nokia spokesman Mark Durrant said “We continue to support Flash and several other technologies”.

Nokia adopts Microsoft’s copy protection software PlayReady and added access to Windows Live services to its cellphones in the year 2007.
