Caitlyn Jenner in ‘I Am Cait’ (New York Daily News)

Last night, “I Am Cait” premiered on the E! network. The eight-part docuseries follows Caitlyn (born Bruce) Jenner as she transitions from a man to a woman, and how that changes affects her relationships with family and friends. The series was announced right after Jenner’s groundbreaking “20/20” interview with Diane Sawyer in which she revealed she’d be transitioning.

With the overnight ratings in, the premiere garnered a 2.1 household rating within Nielsen’s 56 metered markets. It tied with TNT’s “Falling Skies” for the most-watched cable program of the night. Prior similar ratings points to this share being equivalent to about 3M viewers.

These ratings suggest that the interest in Jenner’s story is there, and substantial. I’ll be looking forward to seeing how these ratings progress on a weekly basis.
