Say hello to Yahoo's new logo. After changing its purple wordmark every day for the past month, Yahoo revealed the winner tonight. It's part of an effort from CEO Marissa Mayer to inject some fresh visual interest into the venerable tech brand, while keeping the familiar color and exclamation point.

It's been a big year or so for the logos of prominent tech companies. MotorolaeBay, and Microsoft have all introduced new looks during that time. More recently, YouTube started using a different logo for its apps.

Yahoo put together a video (above) to show off the construction of the new logo, and we've created a GIF showing all the logos of the past 30 days. If you're interested in design opinions and a bit of the backstory leading up to the new design, be sure to head over to AdAge.

Update: Yahoo CEO Marissa Mayer has posted a behind-the-scenes look at exactly what went into the company's rebranding. It turns out Mayer herself played a pivotal role, working with Yahoo's design team (and an intern) to design the new logo over the course of a single weekend. "I’m not a pro, but I know enough to be dangerous," Mayer says of her Adobe Illustrator know-how. "We knew we wanted a logo that reflected Yahoo — whimsical, yet sophisticated," she writes. "Modern and fresh, with a nod to our history." Mayer goes into great detail on various decisions that led to the final design, including font weight, an intentional lack of straight lines, and an attempt to preserve the feel of Yahoo's now former logo.

Before the design process started, company employees were polled for suggestions, with 87 percent voicing support for a revamped brand. And yes, Yahoo toyed with the idea of moving to an all-lowercase logo. "But, in the end, we felt the logo was most readable when it was all uppercase, especially on small screens," Mayer says.
