I want to know the answer to the following question:
When did Fox announce the following season would be Idol's last?
All the background I'm provided with is that "The continuing decline influenced further changes for season 14, including the loss of Coca-Cola as the show's major sponsor, and a decision to only broadcast one, two-hour show per week during the top 12 rounds (with results from the previous week integrated into the performance show, rather than having a separate results show).". Is that enough to answer the question?
