Read this: From the 1987 season until the late 1990s, the most exposure the league would receive was on ESPN, which aired tape-delayed games, often well after midnight, and often edited to match the alloted time slot. The league received its first taste of wide exposure in 1998, when Arena Bowl XII was televised nationally as part of ABC's old Wide World of Sports.
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): In the early years of arena football, after what hour were games often aired?
midnight
