Finally, the day we’ve all been waiting for has come. The new Windows 8 operating system will go live at 11:15 AM EDT in New York, as part of a press conference that’ll also witness the debut of the new Surface tablet. Of course, Microsoft remains tight-lipped on the event and refuses to provide more information on what to expect, but it did mention that Steve Ballmer would not only unveil the new operating system, but he would also say a few words about the Surface. In addition, Microsoft also hinted yesterday that it’ll also start its so-called marketing blitz with the biggest Start Screen ever placed in New York’s Times Square, in an attempt supposed to help people get used to the new Windows 8 feature a bit faster. “And we will be hosting a hands-on experience on the ground in Times Square and at our Microsoft Stores in the North America for consumers to touch and try the new Windows —and maybe even see yourself up on the boards in Times Square,” Microsoft’s Brandon LeBlanc said yesterday. Windows 8’s marketing blitz however is a much more ambitious plan and the Redmond-based technology company is even planning to air ads during the UEFA Champions League matches. “The campaign will include television commercials along with print ads, banner ads online, outdoor posters and branded-entertainment elements such as the musical show La Voz in Mexico, the iconic MTV European Music Awards in Germany, and the popular UEFA Champion League in Ireland which will last into the New Year,” Microsoft said.
