What do Michael Jackson, Twitter and Swine Flu have in common? Answer: They were all among the most common search terms this year, according to reports released by the big search engines.

Notable presences included not just Michael Jackson — who led the fastest-rising list globally — but also pop singer Lady Gaga, who weighed in at No. 7.
