I've been following the story since it broke and it has been interesting to see it all unfold. As for why now....well, allegations actually popped up about 10 years ago and the women that accused him, were vilified and shamed publicly for doing so. He settled out of court with one of them. So there was no incentive for other women to come forward given the backlash the few that did speak out. As for now, it actually got new life when a comedian did a bit in his stand up about the allegations and that video went viral, prompting one, then another and then another and so on to come forward. Now it's taking on a life of its own.
