When did Tiger Woods reveal his affairs?

Answer 1

He, as you probably know was involved in a car crash on the night of Thanks Giving 2009. There was speculation at this time that he was having an affair with Rachel Uchitel, they had apparently been texting that night, and that is how Elin discovered that affair. He didn't really reveal them at all, he paid most of the women great sums of money for their silence, but once the main story broke around 18 came forward to tell their stories. He made a public statement in February where he basically told the world what they already knew and apologised for his actions.
