Twitter just released their top trends for this year, and it gives a very good idea of what happened in 2010. 25 Billion tweets were sent in 2010, and Twitter is nice enough to give us the categories on their #Hindsight2010 page. Looking at these, its pretty obvious that Twitter is becoming an excellent form of up to the minute news aggregation.

The World Cup was also a big deal on Twitter – with “Vuvuzela” featuring in the top trends. Sorry, no #Jujufriday!

Overall Top Trends

1. Gulf Oil Spill
2. FIFA World Cup
3. Inception

5. Vuvuzela
6. Apple iPad
7. Google Android
8. Justin Bieber

10. Pulpo Paul

In the political arena, some of the most popular searches included firebrand ANC Youth League President, Julius Malema, who pipped Helen Zille of the Democratic Alliance and Mvume Dandala of COPE as the third most searched for politician. Despite having a high volume of searches to his name, the Youth League president had to make way for his seniors, Jacob Zuma and Nelson Mandela who demonstrated their staying power by leading the rankings.

Former Springbok Joost van de Westhuizen had us all scrambling for our keyboards and heading for the Google search box when he released his biography. Joost’s relatively late entry into the gossip columns meant he was no match for perennial celebrity, DJ Sbu from youth radio station YFM who led the ‘most for searched for celebrity’ category. He was followed by socialite Khanyisile Mbau. Benoni-girl done good, Charlize Theron, was not to be outdone coming a close third in the rankings. In the sports category, the Super 14 rugby was the most searched for item, followed closely by the Indian Premier League (IPL) cricket, which was quite an achievement as the event was moved to South Africa from India at a late stage in the planning process. Surprisingly, the Confederations Cup was fourth in the rankings despite it being a prelude to the 2010 World Cup, following the third placed Cape Argus cycle race.

This year’s Zeitgeist also reflects important South African concerns, such as understanding how the recession has impacted the local economy. In addition, recession-related keywords such as ‘recession jokes’ showed that not everyone was taking the recession so seriously. South African consumers have also adapted to the recession by being on the lookout for a good bargain, reflected increasing searches for goods in the second hand market on website such as Gumtree and Junkmail Cars.

In addition to telling us what people are curious about in South Africa, Google Zeitgeist tools also offer insight into which topics were of interest across the globe. Top search terms from over fifty countries appear on our Google Zeitgeist webpage, google.com/zeitgeist2009 — from popular song lyrics in New Zealand, to top bargain-hunting websites, to electronic brand searches in Hong Kong.

This year’s global fastest rising searches show interest across pop culture (with the King of Pop at the helm, followed by searches for movie New Moon and singer Lady Gaga), social networking sites and new technologies such as Windows 7 and Torpedo Gratis.
