I know that I’m much more likely to say “Just one more!” when it comes to episodes of TV than feature films, and Netflix has a pretty stellar variety of TV offerings.
The streaming service offers plenty of movies to fill a queue, but movies generally aren’t meant for binge sessions.
All things considered, it’s likely that the increases in viewing hours is related to Netflix’s library of TV shows.
Although the website has been dropping channels and focusing on original content in recent years, there are still plenty of long-running series from days gone by that can be watched for days on end.
