As mentioned earlier, there's been big news from the US on the future of Silicon Valley - the Department of Justice (DoJ) is going to investigate large tech firms like Facebook, Google and Amazon to see if they are just too big.
The BBC's North American technology correspondent Dave Lee told BBC Radio 4's Today programme that the DoJ is looking into how market-leading platforms have achieved market power and are engaging in practices that might have reduced competition, stifled innovation, or otherwise harmed consumers.
"How did Silicon Valley companies get so big without anti-trust mechanisms kicking in?," he said.
"It could lead to some of these big companies being broken up. Facebook might be forced to separate Instagram into one company, WhatsApp into a different company, and the main Facebook app into another one."
