In their blog post, Google talked about social media, music news this year, and in the fastest falling trends held some surprises as well.
So what has captivated the minds of searchers around the world this year? As millions of fans said goodbye to the King of Pop, Michael Jackson led the list of our top 10 fastest rising queries across the globe. And a new star was born, too — quirky pop singer Lady Gaga became a search sensation the world over. In addition to appearing on many regional fastest-rising search term lists, from the Czech Republic to Switzerland and Kenya to the United Kingdom, Lady Gaga also landed in the #9 spot on the global fastest rising list.
…the social web is alive and well. In a sweeping confirmation of the web’s ability to connect us, both Facebook and the Spanish social-networking site Tuenti appeared on the fastest rising searches at #2 and #3 respectively. Twitter also made our global list for the first time at #5..
A grouping of the fastest rising, and falling trends, can be found on Google’s Zeitgeist of 2009.
