Thanksgiving question

How come Detriot are always featured on Thanksgiving?

I know its a long-standing tradition, but how did it come to be?

Also, didn't it always be the Lions playing the Cowboys, or is my memory playing tricks?!?

Why do the Detroit Lions always play on Thanksgiving?

The first owner of the Lions, G.A. Richards, started the tradition of the Thanksgiving Day game as a gimmick to get people to go to Lions football games, and to continue a tradition begun by the city's previous NFL team.

In 1966, the Dallas Cowboys, who had been founded six years earlier, adopted the practice of hosting Thanksgiving games. It is widely rumored that the Cowboys sought a guarantee that they would regularly host Thanksgiving games as a condition of their very first one.

The two "traditional" Thanksgiving Day pro football games have then been in Detroit and Dallas. Because of TV network commitments, to make sure that both the AFC-carrying network and the NFC-carrying network got at least one game each, one of these games was between NFC opponents, and one featured AFC-NFC opponents. Thus, the AFC could showcase only one team on Thanksgiving, and the AFC team was always the visiting team.

Wikipedia has plenty more info too.

Cheers guys, I knew I could of google'd it, but preferred to ask the experts.
