Microsoft's updated corporate logo was revealed yesterday. The last update was 25 years ago (1987). The old logo is below. Choosing a logo is part of the product planning process. An effective logo projects the personality of a product, service, or company. Customers use the logo to identify the product, service, or company. (Try the Logo Quiz at http://www.logoquiz.net/ .) The new logo precedes Microsoft's new software products -- Windows 8, Windows Phone 8, Xbox services, the next version of Office. Here's how Jeff Hansen , General Manager, Brand Strategy, Microsoft , explained the new logo. "The logo has two components: the logotype and the symbol. For the logotype, we are using the Segoe font which is the same font we use in our products as well as our marketing communications. The symbol is important in a world of digital motion (as demonstrated in the video above.) The symbol's squares of color are intended to express the company's diverse portfolio of products." Many companies have wasted a lot of money on their new logos. Consumers don't recognize them or remember them. It is inefficient for the same company, selling the same product, to change their logo. But, what about Microsoft? Was it time to change the logo? How will the new logo inspire the quality and integrity of the new software products?
