Microsoft has released a list of the most popular overall searches on Bing during 2010 and, as usual, topping it are celebrities, including Kim Kardashian who nabbed the top spot in overall search and was the most popular person in the people category. That's a stark contrast to 2009's list, where Twitter, swine flu, the stock market, and cash for clunkers grabbed some of the top spots.

Here's the full rundown:

Most popular overall 2010 searches on Bing: 1. Kim Kardashian 2. Sandra Bullock 3. Tiger Woods 4. Lady Gaga 5. Barack Obama 6. Hairstyles 7. Kate Gosselin 8. Walmart 9. Justin Bieber 10. Free

Of special note here is Justin Bieber, who became so popular on Twitter, that the company reportedly had to add extra infrastructure to handle Bieber-related tweets. The so-called "Bieber fever" also led to the creation of a browser extension that would completely remove traces of the singer from casual internet browsing.

Most popular people searched in 2010 on Bing: 1. Kim Kardashian 2. Sandra Bullock 3. Tiger Woods 4. Lady Gaga 5. Barack Obama 6. Kate Gosselin 7. Justin Bieber 8. Jesse James 9. Lindsay Lohan 10. Jennifer Aniston 11. Michael Jackson

Michael Jackson was 2009's top searched-for term overall, given the musician's death in late June of that year. This year, Jackson was No. 11 in the people category.

Neither Yahoo nor Google has released its most searched-for terms yet, though for Google this has typically been done in the first few weeks of December. A Google spokesperson told CNET that 2010's list is being released a little later than usual this year to capture more data.
