Times Online:

On the evening of Saturday January 17, 1998, the internet gossip merchant Matt Drudge posted a story that opened the most sensational scandal season in the history of the American presidency. He reported that Newsweek magazine had killed a story about President Clinton’s sexual relationship with a former intern. The next day he had her name: Monica Lewinsky.
The mainstream media were slow to catch up, but by the following Tuesday they were reporting that Clinton was being investigated for encouraging others to lie to cover up the affair.
