The Hollywood Reporter has learned that Aquarius will not be returning to the air for a Season 3. The drama was originally picked up straight to full series and premiered in the summer of 2015. After airing the first episode, NBC decided to post the entire 12 episode season online for streaming, which was made available for four weeks. This made Aquarius the first broadcast show in TV history to use this unique marketing strategy. The odd move was seen as an experiment at the time, but now it looks like just the first step to the show's eventual cancellation.
