麻豆约拍

An experiment removing unpaid news posts from Facebook users' main feeds alarms media firms relying on the social giant for viewers. We ask Joshua Benton from the Nieman Journalism Lab whether publishers are right to be worried. Plus, Twitter bans ads from some Russian sources and pledges to reveal the origin and funding of political advertising. Are Facebook and Twitter feeling the heat over accusations they help foreign powers to influence elections? Roland Lamb, the creator of the ROLI Seaboard musical instrument chats to us about star endorsements in tech as he brings Pharrell Williams on board his venture. And, we visit The Glass Room, an exhibit that looks like a technology store but aims to show people how much private data they give away online. Presented by Rory Cellan-Jones, with 麻豆约拍 tech reporter Chris Foxx, and special guest Keith Collins from the Quartz news site.
