Dive summary: 

• The wait is over: Yahoo unveiled its new logo Thursday.
• The new logo is a darker shade of purple with a sans-serif font created by Yahoo; the sleeker logo is still rocking the signature exclamation point, which in some versions dances. 
• Yahoo revealed two versions of the new logo on its Tumblr at midnight Thursday; one with purple lettering on a white background and a reversal with white lettering on a purple background. 

From the article: 

"Yahoo managed to turn a simple rebranding into an impressive marketing push by dragging it out for 30 days. For the past month, the company has rotated out the logo on its homepage daily with one of the runners up. Some of the 29 logos were a lot more unusual there than the final choice, perhaps to make fans appreciate the reserved simplicity of the final look."
