Netflix has analysed its global streaming data to discover the exact episodes that got people hooked on its most popular TV shows.
The streaming service picked out the episode of a show's debut season which - after it was viewed - kept 70 per cent of people watching for the rest of the season or more.
Traditionally, a TV show's pilot episode has made or ruined its success on the airwaves, yet Netflix found that most people got hooked on a series later into its run - suggesting that its model of dumping entire seasons onto the platform at once can be more effective at building a loyal audience.
Here's the particular episodes of popular series that got people glued to their couch:
