On its TCA day, NBC announced a renewal for This is Us not just for the 2017-18 season but for the 2018-19 season as well. A renewal of the breakout hit was just a formality but the two season pickup is an extra show of support.
This is Us is far and away the #1 new broadcast show this year, hitting a series high 3.0 demo last week. It has a ton of buzz and critical acclaim to boot. It will likely stay in its Tuesday 9pm slot next season (perhaps leading into a new show) and also will likely continue to do 18 episodes a year. This is Us joins The Voice as official NBC renewals for next season.
