Nearly two weeks ago, Yahoo! released its new logo. The company launched a campaign in which they released a new logo for 30 days, culminating with the final version on day 30.

Now that the dust has settled, I want to spotlight how Yahoo! used social media to tell its story. Hang in here with me, there are lots of links so you can follow along for yourself.

The ’30 days of change’ campaign launched with a Tumblr post by Yahoo! Chief Marketing Officer Kathy Savitt. She wrote of the recent changes at Yahoo! and the desire to bring the 18-year-old brandmark into its new era as well. Culminating her post, she linked a YouTube video titled ‘Yahoo! 30 days of change.’

And so began the project. Yahoo! posted a logo each day and made it easy to follow on social media outlets. Twitter users could join the conversation utilizing a #dailylogo hashtag. Facebook users could comment underneath the post and Tumblr users commented and reblogged posts.

At the culmination of ‘30 days of change’, Savitt once again took to Tumblr to reveal the final logo design and post an artistic video detailing the final product. What’s even cooler is that Yahoo! CEO Marissa Mayer gave a behind-the-scenes look at the design process on her own Tumblr page.

All this being said, I think Yahoo! did a great job utilizing their digital and social channels to tell a unified story. Messages were tailed to the strength of each platform. Twitter allows hashtags to unite conversations, Tumblr enables long posts for in-depth thoughts, YouTube is engaging, and Facebook allows billions of users world-wide to take part. Social media employees at Yahoo! realized these strengths and more than likely created a plan to use each one.

Did ’30 days of change’ drastically change company strategy? Probably not. But for a mature company headed in a new direct, energy and excitement is reassuring and Yahoo! proved social media can be the perfect tools to do so.
