Carrie Underwood's debut scored 5.9 million viewers

Carrie Underwood's debut as a judge on American Idol attracted 5.9 million viewers, surpassing Katy Perry's last season premiere by over one million. The Season 23 premiere on March 9 drew 4.5 million viewers, lower than both Underwood's introduction and Perry's previous season. Underwood, a Season 4 winner, joined judges Lionel Richie and Luke Bryan. Perry announced her departure after seven seasons to focus on her music career. Viewer reactions have favored Underwood, with many expressing their preference for her judging style. Despite her successful debut, Underwood's recent performance at President Trump's inauguration has reportedly created tension on set. Sources indicate she has been polite but distant with the crew, and staff have been advised not to discuss the inauguration.
