Before WWI, few football fields had loudspeakers to announce the happenings on the field. Audio and lighting technologies advanced after WWI, leading to loudspeakers and lighting systems being installed to keep fans informed and allow night games. Still, the technologies remained primitive by our standards. The lights were not as bright, and the speakers were not as loud, often leading to them being installed between the field and the stands. Even at relatively big-time football programs, loudspeakers and lighting poles obstructed the view of portions of the field.
