Every Witch Way had been renewed for season 4 as upfront mentioned on last February, and just finished airing all episodes just last week. It was confirmed that it's ending and won't get renewed for another season.

However there's Every Witch Way spinoff, WIT Academy which will air in fall 2015.

It's a strategy that might have mixed results, but it's a strategy. That and going cheap, cheap, cheap with Every Witch Way and the other Caterina Ledobear shows. So cheap that they can post profits no matter how bad the ratings are, and it's just dumb luck (and in my opinion a testament to Ledobear's talent) that they happen to be pulling in almost the same ratings on daily throwaway slots as the prime Saturday premieres. It's the same thing with Max & Shred and Make It Pop! - import shows from Canada where someone else already sunk the costs in for you, or even pitch in a little bit but it's still less than making a show entirely yourself, even if it's a single-cam with a major song number in every episode like Make It Pop!
