China Central Television is planning an interactive Web site for the Beijing Olympics in partnership with MySpace China and Tudou.com, an online video site, The Wall Street Journal reports. It will be viewable only in China, so it won't compete directly with Microsoft's own site, which it's producing in partnership with NBC Universal.

That site, www.nbcolympics.com, was announced during Bill Gates keynote address at the Consumer Electronics Show earlier this year. It's expected to offer some 2,200 hours of live event coverage from the games with up to 30 streams of full-screen content to choose from. It will be based on Microsoft's new Silverlight technology, which competes with Adobe's Flash -- the widely used online multimedia player that powers YouTube and other popular Internet video destinations.

Advertising agency Crispin Porter & Bogusky has won the Windows account at Microsoft. The company is reportedly preparing a $300 million campaign, according to sources cited in this Advertising Age story. The campaign would seek to promote the operating system with consumers later this year, probably to coincide with the release of Service Pack 1 for Windows Vista. Given the beating Vista has taken in the "I'm a Mac. I'm a PC" campaign for Apple, it will be interesting to watch how aggressive Microsoft and Crispin are willing to be in this next wave of promotions for Vista.

Google Sites, a retooled JotSpot, is getting headlines today as a competitor to Microsoft SharePoint. Microsoft will be making noise about SharePoint next week when it hosts a conference here in Seattle devoted to the software for collaboration among work groups. Bill Gates is scheduled to give a keynote on Monday morning. I wonder how much execs will entertain comparisons of their technology with what Google has on offer.
