High-Flying Tech

First came driver-less cars. Now Google reveals it is working on planes without pilots. A key adviser to Facebook is urging the company to protect users from stumbling across gruesome videos by making them click their consent before they can view them. We speak to him and ask whether access to such content is justified in the public interest to reflect the state of the world around us. Why has retail giant Amazon stumped up nearly $1billion to buy a niche video-streaming service popular with gamers? We'll ask one of the stars of the site whether he's worried it will lose its character under Amazon's ownership. And as a video blogger who posted a film complaining about the misogynistic portayal of women in computer games herself becomes the target of hate messages and threats, we discuss whether her concerns are justified, and how to address them if they are.

Presented by Zoe Kleinman, with Leo Kelion and Dave Lee from the BBC Online Tech Desk and special guest Eileen Burbidge, venture capitalist from Passion Capital.
