Jeff Bezos is another tech billionaire who's been in the news, though it's matters terrestrial that concern the owner of Amazon.

Mr Bezos stands accused of deliberately killing off the Washington Post, the newspaper he bought in 2013.

The Post announced this week it was cutting a third of its workforce and Saturday saw the chief executive, Will Lewis, resign.

The Washington Post's official slogan is Democracy Dies in Darkness.

Many of its staff say these sweeping cuts made a mockery of that motto.

Much of their anger has been directed at the paper's billionaire owner, Jeff Bezos, and the man he appointed as its publisher two years ago, Will Lewis.

The British journalist has proved a divisive figure at the Post.

Under his leadership, it's failed to reverse heavy financial losses and tens of thousands of readers cancelled their subscriptions when Mr Bezos stopped the paper from endorsing Kamala Harris during the last presidential election.

Mr Lewis reportedly angered staff even further by not showing up to the video call announcing the job losses.

The task of explaining the cuts was left to the Post's executive editor, who said the decision was painful but insisted it would bring stability and help reinvent a struggling business model.

Mr Lewis has now told colleagues it's the right time to go.

He said difficult decisions had been made to ensure the Post could keep delivering high-quality news.

He's been replaced by the chief financial officer.
