Bing and Yahoo have already announced their lists of the most popular search terms of 2009, and now it's time for the undisputed, heavyweight champion of search - Google, in the red trunks - to announce its rundown.

In their annual Zeitgeist report, Google crowns "Michael Jackson" as the fastest rising search term, followed by "Facebook" in second place and "Twitter" in fourth place, with Spanish Facebook "Tuenti" coming in third place.

As far as the fastest falling search terms go, unsurprisingly the heaviest hitters of old, such as "Beijing 2008″ and "Euro 2008," have decreased in relevance, and certain Internet giants, such as eMule and Bebo, have obviously lost their luster.

The full list is below:
