As of early this morning, Uber’s CEO Travis Kalanick is out.

It’s the latest chapter in what has become perhaps the most enticing tech story of the year that, many might argue, begins with the bombshell letter released by Susan Fowler that discusses rampant sexism inside Uber.

Things started to sour earlier this year, however. Here’s how it all went down:

• December 14: Reports reveal Kalanick is joining Trump’s business advisory board

• February 20: Uber calls for an internal investigation, known as the “Holder investigation” after Eric Holder, who’s leading it.

• February 23: Alphabet’s Waymo unit files a lawsuit against Uber claiming that a former Waymo employee, Anthony Levandowski, stole secrets related to autonomous vehicle technology.

• February 28 Travis Kalanick apologizes after he’s caught on film arguing with an Uber driver Fawsi Kamel about Uber’s new plans to lower fares. “Some people don’t like to take responsibility for their own s—. They blame everything in their life on somebody else. Good luck,” Kalanick told his driver.

• March 3: The New York Times reveals that Uber has been using a feature named “Greyball” that showed suspected city officials a fake version of the app that would deny them a ride. This was used by Uber to operate in areas where its service was deemed illegal without being caught.
