Why do we binge-watch?

What makes us binge-watch shows like Killing Eve or Game of Thrones? And is it a problem - or could it actually be good for us?

The term "binge-watch" was a contender for the Oxford English Dictionary's 2013 Word of the Year. Although it didn't win ("selfie" ultimately took the crown), this pointed to the rise of what was becoming a popular activity of watching multiple episodes of a TV show in a single sitting.

Today, millions of us regularly consume our favourite series in this way. The proliferation of streaming services over recent years has made it very easy to do.
