How rough a year has it been for Uber? Rough enough that the latest news that broke overnight--and that could affect its ability to serve 500 million potential customers in Europe--was only about the seventh-toughest challenge the company has faced during 2017.

Yes, Uber is still an amazing company. Yes, its founder and former CEO Travis Kalanick is worth more money than most of us will ever see. But its most important new investor wants to slash 20 to 30 percent off its $69 billion valuation as it pours in more cash, and the organization is still recovering after the sexual harassment and culture allegations that rocked it earlier this year.

So 2017 comes to a close, here's a quick recap of how Uber will remember the year--or perhaps try not to.


About 400,000 people delete their Uber accounts after the company surges prices during a massive protest against President Trump's travel ban. CEO Travis Kalanick soon resigns his seat on Trump's economic advisory council. Meantime, the company has to move its self-driving car program to Arizona after its home state, California, revokes its license. 


Former Uber engineer Susan Fowler publishers her groundbreaking and viral essay exposing the sexist culture at Uber and in Silicon Valley. Kalanick, then 40, issues an apology--but it's about a video that emerges of him berating an Uber driver. He says he needs to "fundamentally change as a leader and grow up."


In the wake of Fowler's essay, Uber starts shedding executives. Its vice president of product and growth, Ed Baker, resigns.


Anthony Levandowski, head of the company's self-driving program, steps aside during litigation brought by his former employer, Google, which alleges he stole documents from his old company before departing. The next month, he's let go outright.


The Justice Department in Washington says it's investing Uber's use of "greyball" software in order to evade regulators.


Kalanick takes a sabbatical and is then quickly forced out of the company (although he retains his board seat). Uber fires 20 more employees as a result of its investigation into its own workplace culture. 


Uber's relationship with drivers takes a hit, and news reports investigate "dangerously long shifts" to take advantage of fleeting incentives and bonuses.


After an extensive search, Dara Khosrowshahi takes over as CEO. Meantime his predecessor, Kalanick, is sued by one of his original investors for allegedly "with[holding] important information about Uber's mismanagement prior to the board's June 2016 decision to give Kalanick authority to create three new board seats."


The city of London announces it's going to deny Uber an operating license, potentially kicking it out of one of the biggest and most profitable cities on the planet. (Its first CEO, Ryan Graves, who got the position after responding to a tweet in 2010, also leaves.)


Kalanick still has a board seat, but the rest of his fellow board members make a bunch of moves to limit his power, including vastly expanding the size of the board itself.


News breaks that Uber suffered a massive data breach in 2016, potentially disclosing the personal data of 57 million customers. The company paid $100,000 to hackers as ransom, and the story didn't break until a year later.


Rounding out the year, the European Union's highest court decides that Uber isn't an app company--it's a taxi service, opening the door for a market of half a billion people to regulate it much more closely.
