Submission + - Comedian saying 'Google it' caused Bill Cosby's downfall (saportareport.com)
The allegations against Cosby have been public since 2005 (http://www.vulture.com/2014/09/timeline-of-the-abuse-charges-against-cosby.html), when 13 Jane Doe victims testified on behalf of Andrea Constrand. However,
"it was not until someone made a cell phone video of a standup routine which a young comedian named Hannibal Buress had been doing for several weeks, that the story ignited. There was nothing new in what he said — there have even been previous comedy routines about the rape allegations — except this: “You leave here and google ‘Bill Cosby rape.’ It’s not funny. That s*** has more results than ‘Hannibal Buress.’”
Somebody put the clip up on a Philadelphia magazine’s website, and a lot of people did what Buress suggested. In a cosmic piece of bad timing, Cosby’s website put up a meme generator, which allowed readers to write a headline on a picture of the star and post it on social media sites. That helped fan the now-flickering flame, which gained force as one after another woman came forward to accuse him.
Baxter also posits that "it's inevitable that there will be efforts to control access to the scattered bits of information that could create a media fire, as well as malicious attempts to strike matches."
