Yahoo has been on a major change drive, snapping up companies, changing up human resources policies and redesigning products. Now, it hopes to translate that change into a new logo, which will be debuted next month. To tease that, it now going to display a "new" logo on its homepage and network in the U.S. every day, for the next 30 days. Call it their version of a Google Doodle, but at least according to the video, all that seems to be happening is a change in the font and kerning each time.
Unfortunately, the yodel, the exclamation point and purple aren't going anywhere. You can follow the new logos on Yahoo's tumblr.
