What is social media and how did it grow so quickly?

You’re more likely than not to have used social media recently, and it’s also likely that the time you’ve spent on the platforms has clocked up at least several hours a month. For instance, 99 per cent of people aged 16-24 in the UK in 2016 said they had used social media within the past week, while they spent close to an hour a day using it to communicate.
