It's been hard to avoid the vast number of stories about CES 2018, the largest technology show of the year, this week. However one fact about the event has received less attention: there were no female keynote speakers. Not even one.

Perhaps we shouldn't be surprised. After all, this revelation comes hot on the heels of a year that saw a vast number of stories about the technology sector's sexism and lack of diversity.

Even a seasoned observer of the technology industry might be surprised to learn that 'diversity in tech' was the fourth most covered technology story in the UK in 2017.

More than 7,600 articles were written about the subject, only beaten by WannaCry, Apple and Donald Trump's tweets, according to data compiled by Signal Media.

So what did these stories cover? Here's our overview of the biggest sexism scandals within tech in 2017 and 2018 so far.

Susan Fowler blows the whistle on Uber

In February 2017 Susan Fowler, a former engineer at Uber, published a blog post in which she described the sexual harassment she had experienced while working at the company. She writes that her boss propositioned her for sex on the first day she joined his team, she complained to HR, but rather than take action against her boss, Fowler was pushed to leave the team. This post has been described as the 'first shot' in a series of revelations about sexism in Silicon Valley. It resulted in the firing of 20 employees and added to the pressure that resulted in Uber founder Travis Kalanick stepping down as CEO.

Venture capitalists and top tech figures accused of sexual harassment

In June 2017 it emerged that a high profile venture capitalist called Justin Caldbeck had been accused of unwanted sexual advances by six female founders. This proved to be the first in a series of allegations against high-profile VCs, including Dave McClure, founder and CEO of 500 Startups, and Chris Sacca of Lowercase Capital. The allegations were not confined to just VCs however, with blogger and tech evangelist Robert Scoble also accused of inappropriate advances by a number of women in the technology industry.

Google engineer pens 'anti-diversity' memo

In August 2017 a Google engineer published an internal memo arguing that the lack of women in top tech jobs was rooted in biological differences between men and women, rather than sexism. The author, James Damore, was fired by Google just days later. In January 2018 it emerged that Damore was suing Google for 'unfairly discriminating against white men whose political views are unpopular with its executives'.

No female keynote speakers at CES 2018

The Consumer Electronics Show, which took place 9-12 January 2018, failed to secure any female keynote speakers for the second year running. It since responded to the backlash by adding two female keynote panellists, but it remained the case that none of the solo speakers on the main stage were women.
