Netflix is the undisputed leader in streaming television with some 140 million paying subscribers in 190 countries and territories and hit shows like "The Crown," "House of Cards" and "Stranger Things."

Netflix gained popularity with "catalog" shows and movies from Hollywood and television studios but has been investing heavily in its own content in recent years. It may be vulnerable, according to analysts, if it loses access to these shows since it does not have other revenue from services or products to subsidize its streaming.
