Search engine Lycos says it has beaten the record for the most searched event over a one-day period - a position previously held by the September 11 attacks on America.
Janet Jackson received 60 times as many searches as the Paris Hilton sex tape and 80 times more than Britney Spears.
Jackson's breast was bared when fellow performer Justin Timberlake ripped off her bodice during a half-time performance in front of almost 100 million television viewers.
Digital recording company TiVo says it was also one of the most watched moments in US TV history - as subscribers paused and replayed the incident.
Jackson, Timberlake, CBS and half-time show producers MTV have all apologised for the spectacle.
Jackson and Timberlake will appear at next week's Grammy Awards despite the scandal, officials have said. But the broadcast will be delayed to weed out any more surprises.
The move by CBS came after the powerful Federal Communications Commission launched an inquiry into the scandal.
