The Live+Same Day numbers reported in our ratings column do not reflect a show’s overall performance, given the increased use of delayed playback via DVR and streaming platforms, plus out-of-home viewing. These numbers (Nielsen fast nationals, unless denoted as finals) instead aim to simply illustrate trends or superlatives. This is only an exhibition, not a competition — please, no wagering.
