I want to know the answer to the following question:
When did Coca-Cola stop being a sponsor of American Idol?
All the background I'm provided with is that "The third major sponsor AT&T Wireless joined in the second season but ended after season 12, and Coca-Cola officially ended its sponsorship after season 13 amidst the declining ratings of Idol in the mid-2010s.". Is that enough to answer the question?
Answer: yes
