Final answer:
Broadcast networks often air syndicated programs during fringe time, which is just before and after primetime, to fill programming schedules with a variety of content.
Step-by-step explanation:
Broadcast networks might air syndicated programs during fringe time, which refers to the time slots just before and after primetime hours. These off-peak times are often used to broadcast syndicated content that local stations acquire to fill their schedules. Syndicated programs can include a vast array of show types such as gameshows, talk shows, and reruns of previously popular programs. While broadcast networks have traditionally aired syndicated content during daytime and evening slots, the specific timing can vary and includes periods outside of primetime to attract specific audiences or fill gaps in the programming schedule.
