Net Firms Face Fines

Google faces a fine of $2.7bn by the European Commission over a competition ruling on its shopping service, and Germany passes a law that requires internet firms to take down illegal content within 24 hours of being reported or face big penalties.

Plus, will artificial intelligence be a useful tool in computer security? Emily Orton of security firm Darktrace tells why she thinks so. Presented by Rory Cellan-Jones, with BBC Online tech correspondent Mark Ward, and special guest Kate Bevan, journalist and computer security specialist.
