E! network is cancelling "I Am Cait" after two seasons.
The reality series chronicled the life of Caitlyn Jenner, formerly been Bruce Jenner, the TV personality and Olympic athlete.
It debuted a year ago to huge fanfare (and 2.7 million viewers) as part of a publicity drive accompanying Jenner's transition from a man into a woman.
Jenner's stepdaughter Kim Kardashian and husband Kanye West, as well as her ex-wife Kris Jenner made appearances.
After 2 amazing seasons of @IAmCait, it's time for the next adventure. Thank you E! & thank you to the best girlfriends I could ask for!

A second season aired in March and April of this year. But the average audience had sunk to about 700,000 viewers.
In a statement, E! said: "Caitlyn and E! have mutually decided not to move forward" with another season.
It added that Jenner will continue to appear on Keeping Up With the Kardashians.
