According to Amazon CEO Jeff Bezos, sci-fi program 'The Expanse' will return on Amazon Prime. As of now there's no fixed date for the show's fourth season premiere. Despite praise from critics and audiences, a 25% drop in ratings for 'The Expanse's' second season and a further 5% fall in season three led the Syfy channel to cancel it earlier this year. 'The Expanse' is no stranger to streaming platforms as its previous seasons are currently available on Amazon Prime in the United States and on Netflix in the United Kingdom.
