In regards to its late night lineup, Fox had already decided to cancel The Late Show, and had a replacement series in development, The Wilton North Report, when the former series began a ratings resurgence under its final guest host, comedian Arsenio Hall.
The network added a third night of programming, on Mondays, at the start of the 1989-90 television season, a season that heralded the start of a turnaround for Fox.
