I want to know the answer to the following question:
What happened in 2007-2008 that had a drop in viewers for all networks?
All the background I'm provided with is that "The premiere was down 11% among total viewers, and the results show in which Kristy Lee Cook was eliminated delivered its lowest-rated Wednesday show among the 18–34 demo since the first season in 2002.". Is that enough to answer the question?
