These includes games televised by CBS and NBC on an experimental basis. These games happened in the late 1960s. The pre-1960s games were on Mondays either as special promotions or due to schedule conflicts. The primary reason that Monday games were much more rare before the 1960s was mainly because artificial lighting was not yet widespread or good enough to provide an acceptable view of the field for a night game (hence, for the first few years of night games, a specially painted white football was used), thus requiring that all games be played during the day, when most potential spectators were at work.
