Amazon Studios has created a formula that works. Put out a number of pilots, have your viewers vote for the shows they like, and then quickly turn those top-rated programs into full seasons.
The Man in the High Castle, a month removed now from its second released season and already in production on a third, released its pilot in January of 2015. A month later it was given the green light for a full ten episode season, and just eight months after that the remaining nine episodes were online and ready for streaming.
Emmy winner Transparent premiered its pilot episode in February of 2014, and by that September the rest of the series had dropped. Mozart in the Jungle had an eight month turnaround, and is one of the favorites every time award season rolls around. Even the challenging production of a multiple location shoot like Bosch took less than a year to go from green light to full series. Season 3 of Bosch is set to premiere later this year and Season 4 has already been purchased.
