In the 1970s and 1980s, WDIV preempted one to two hours of NBC's daytime programming every day. The station also refused to air "Late Night with David Letterman" and its successor, "Late Night with Conan O'Brien" at 12:35 a.m. for many years, and initially did not clear the Letterman-era program at all. Instead, until 1999, the station opted to rebroadcast "Jenny Jones" in that timeslot, along with off-network syndicated programs such as "Barney Miller". WDIV currently airs the entire NBC schedule, though while "Late Night" now airs at its usual time of 12:35 a.m., it airs "A Little Late with Lilly Singh" at 2:35 a.m. instead of 1:35 a.m. due to a rebroadcast of the 11 p.m. news and an infomercial.
