It broke a record with its premiere, becoming the top time-shifted series premiere on record for NBC with a Live+Same day viewership of 10.41 million people.
After a few days passed for Live+3 day calculations, Manifest bumped its viewership up to 16.13 million.
The premiere scored a ratings win with 3.63 in the key demo.
All things considered, Manifest scoring some additional episodes in Season 1 comes as no surprise.
