Old Bing logo.
So the redesign (mentioned by Bing a couple of days ago) is certainly an upgrade, and more in tune with logos for Microsoft’s other services.
“From the color of our logo to the angle of the cut on the top of the b, the Bing identity has been designed to fit seamlessly into the Microsoft family of products.”
“We’ve taken inspiration from the new Bing symbol by taking all angles to infinity and adding in levels of color and transparency to add depth and energy. We call this the Searchlight graphic as it uses the Bing symbol as a prism of light and inspiration.”
— Scott Erickson, brand and creative
I like to see more context when new designs are shared, such as where those “Searchlights” will appear. I don’t think it does the designers any favours.
