This ride is opening at the perfect time for not just USF, but NBC. Fallon's ratings have dipped by 800,000 viewers per episode in 2016-2017 from 2015-2016 and Stephen Colbert just passed him for the first time since taking over The Late Show.
Obviously the high political climate is helping Colbert, but if he can maintain higher viewership (of which many seem to have jumped from Fallon), Fallon may actually NEED the in-park advertisement if he plans on staying atop the late night ratings.
