But did you know that there used to be a total of four pro football telecasts on Thanksgiving Day? This was indeed the case from 1967 to 1969. During those seasons, CBS presented a pair of Turkey Day telecasts with staggered start times sandwiched around an AFL doubleheader on NBC. The four games represented a whopping 31% of the pro football schedule. During these threee seasons CBS would begin with a noon time game from Detroit. Then NBC provided a pair of AFL games starting in the early afternoon. Finally, CBS came back with a 6 pm game from Dallas. And on top of all that, ABC aired a mid-afternoon college game.
For example, here was the Thanksgiving Day TV menu on Thursday 11/27/1969 (all times ET):
Vikings @ Lions, 12:15 pm, CBS
Broncos @ Chiefs, 1:30 pm, NBC
Texas Tech vs Arkansas, 2:30 pm, ABC
Chargers @ Oilers, 4 pm, NBC
49ers @ Cowboys, 6 pm, CBS
In a notable sign of the times, NBC used a 2.5 hour window for its early game.
