TV Ratings: Caitlyn Jenner's Reality Show Returns to Series Low March 08, 2016 10:28am PT by Michael O'Connell E! series 'I Am Cait' pulls just 745,000 viewers on Sunday night. Caitlyn Jenner returned to E! on Sunday night with the sophomore season of I Am Cait. And the new run, which premiered with far less fanfare, was down in its first same-day showing. Sunday's episode of I Am Cait brought in 745,000 viewers and 0.3 rating among adults 18-49. For its total audience, that's down more than 500,000 from its freshman finale — and nearly 2 million off from the series launch. The real measure of success for I Am Cait, like all series now, is in how it performs after delayed viewing. And E!, for its part, also brings a significant number of Kardashian franchise viewers with encores. But I Am Cait's performance has been under a very particular kind of microscope since its 2015 premiere. Jenner brought a record-setting audience for her 20/20 sit-down a few months earlier. It set an ultimately unreasonable high bar for interest in the show. I Am Cait's first episode brought in a strong sampling for E!, with an average 2.7 million viewers tuning into that first episode and a 1.2 rating in the key demo, but the show's Sunday night audience quickly dipped — though no episode ever fell below the 1-million-viewer mark until the March 8 return. All told, with live-plus-seven day ratings, first-run telecasts of I Am Cait's eight-episode season averaged 2.2 million viewers and a 1.0 rating among adults 18-49.
