This… is American Idol‘s final ratings report.

Fox’s onetime juggernaut wrapped its 15-season run on Thursday night with a total audience of 12.9 million viewers, while scoring a 3.0 demo rating. That marks the reality competition’s best finale numbers since Season 12 (when it closed with 14.3 mil/3.6).

At its peak, Idol drew 38.1 million (!!!) to its Season 2 finale, while its all-time finale low was Season 14’s audience of 8 million.
