Why are they doing this? Microsoft launched a four-month marketing campaign when Windows XP was initially launched nearly four years ago, but this new campaign is much larger. The new 11-country campaign includes 51 TV ads, 39 print ads, 250 online ads, and has 13 themes including cooking, education, entertainment, family and photography Basically we get to 'enjoy' 15 months of Microsoft propaganda on Longhorn. I call it propaganda because most people don't really care. They upgrade when the new thing comes out or stay with what they have. Commercials for the OS aren't really going to effect sales. Businesses almost always upgrade unless there is a must have app that won't run on the new system and home users upgrade when their system gets slow/breaks. Geeks get it to say they have the latest and 'greatest' while gamers get it to keep on playing. Why exactly are they doing this now? When you have 90%+ market share aren't you exempt from advertising for all practical purposes. Its not like someone who doesn't own a computer is going to run out and buy one just to have Longhorn.
