Tech giant Microsoft has re-branded from Bing to Microsoft Bing and changes their logo a little bit. They went from the green, more robotic looking letter B to a more sleek looking letter B and changes the the color to blue. However, on the Bing homepage it still shows the old style letter B and the domain name MicrosoftBing.com redirects to Bing.com

Microsoft also stated that the reason for the re-brand is to continue the integration of our search experiences across the Microsoft family.
