Regulatory bodies around the world are looking to tighten the rules that govern the digital world. Concerned by issues relating to both the web content and the business conduct of some of the big technology companies, legislators from the US to the EU are trying to re-write the digital laws. We look at what this could mean in practice for Silicon Valley. We also look at dry ice – how it works and the important role it will carry out in the distribution of the Pfizer Covid-19 vaccine, as well as the possible implications that could have for the drinks industry. Plus while Zoom business meetings are all the rage now, how long before virtual reality take them to the next level? And we discuss the joy of traditional Christmas correspondence and find out why young people are starting to send greetings cards again. Business Weekly is presented by Lucy Burton and produced by Matthew Davies.
