Half a billion: that's how many hours Netflix users spent all over the world streaming Adam Sandler movies from December 2015 to April 2017.

It started because of a Blockbuster late fee

You've got a late fee for Blockbuster to thank for Netflix— perhaps. Reed Hastings was annoyed when Blockbuster charged him a $40 late fee for not returning Apollo 13 on time, according to the most-told Netflix origin story. Co-founder Marc Randolph later said that tale was more smart PR than truth, but the messaging worked. Blockbuster later passed on an opportunity to purchase Netflix for $50 million

It is bad for your sex life

Secretly binging on House of Cards is not the only way Netflix impacts your relationship without telling your partner. Streaming hurts your sex life as well. Couples are having less sex now than they were in the '90s, going from five times a month to three times a month on average, according to Cambridge University professor David Spiegelhalter.

DVDs by mail was once the core of Netflix’s business. The number of  streaming subscribers has long exceeded the number of people getting  discs via the USPS, but there are still around 4 million people in the  U.S. watching their movies the old-fashioned way. Some are likely among  the 34 million people who don’t have access to broadband internet. Others just want access to  a deeper catalog of movies and shows than you can get via streaming.  Though the number of subscribers is small and shrinking, Netflix says it  has no plans to cut the DVD-by-mail service entirely.

Millions of people are Netflix thieves

The Motley Fool estimated that people who use another person's account to stream content might cost the company $360 million or more in revenue. Over 20% of young people and overall 12% of adults share log-in credentials for sites like Netflix and Hulu. Netflix might have to clamp down on password sharing if revenue growth continues to slow, Fortune predicted.
