To my understanding of the production.
- 2010: Korra is announced at Comic Con. The goal was for a 2011 show and 12 episodes were greenlit. (The original Season 1 miniseries)
- During the production of Season 1 they did not hit their goal for 2011 but also during 2011 Nick decided to have 26 episodes now (Season 1 and 2). The miniseries original idea has now become a TV show.
- Korra Season 1 aired in 2012 during the months of April to June.
- By July 2012 at that Comic Con it was announced that Nick was going to do 52 episodes over a total of 4 books.
- Season 2 aired 2013 Sept to Nov, Season 3 aired 2014 with June to August, Season 4 aired 2014 with Oct to Dec.
I am basing this off one of the two show runners own tumblr blog from 2012. Posted within 24 hours of that comic con 2012 that I referenced earlier.
