US tech giants in Congress showdown

Available for over a year

The bosses of four of America's largest tech firms testified remotely to Congress. Facebook's Mark Zuckerberg, Amazon's Jeff Bezos, Alphabet's Sundar Pichai and Apple's Tim Cook all took part.They faced questions from the House Judiciary Committee on whether their firms have become too dominant. But we hear it is not just an issue in the tech industry. Writer and journalist David Dayen tells us that the US has "cradle to the grave monopoly problem" Also in the programme, we look into why have some French winemakers turned to making hand sanitisers. Plus - we ask how useful are training courses that focus on diversity and unconscious bias. And why is the Netflix series Indian Matchmaking creating such a storm?
