Those were the top three in Google's annual Year-End Zeitgeist ("spirit of the times") ranking of the people, places and moments garnering the world's attention throughout the year, Google Senior Vice President Amit Singhal wrote on the company's blog Tuesday.
The rankings included several Top 10 lists across categories such as Trending People, Most-Searched Events and Top Trending Searches from 72 countries, he wrote.
Nelson Mandela was the No. 1 trending search for the year as interest in the former president of South Africa was high year-long and after his death people turned to Google to learn more about him and his legacy, Singhal said.
The Top 10 global searches were:
Samsung Galaxy s4
Google says it has created a Zeitgeist homepage, http://google.com/zeitgeist, were people can follow the Top 100 trending searches of 2013.
They can also see what the top trending searches were for each year from 2001 on, it said.
