  17. Backstreet Boys

The number one slot belonged to PlayStation 2, which led to the optimistic prognostication "that gaming culture may be on the verge of eclipsing movies and television in the pop culture lexicon."

The terrorist attacks on Sept. 11, 2001, pushed the term "world trade center" into No. 6. The mastermind, Osama bin Laden, registered at No. 15, followed by Nostradamus, due to a hoax that the 16th-century so-called prophet predicted the events. Searches at the time also underwent an "upswing in patriotism. Searches on anthems, patriotic speeches and songs, and the American flag (26) soared as Americans looked for ways to express their support for their country."

Decade of top searches

Since

2001, Yahoo! has dipped into billions of searches to uncover our audience's

curiosities, interests, and what matters most to them. Unlike editorial

retrospectives or surveys, the rankings come from online users’ own search

behavior. Looking back, these lists truly sketch a society in motion: It's a

unique way to gauge social trends and interests in the year’s top stop stories,

compelling newsmakers, and viral fads.

Take a look back at a dozen years of Top 10s to see how the Web has grown — and

see what

preoccupied readers in 2012.
