The media changed it all at once in 2000. They decided in unison that we Republicans would be red, never blue. That way the communistic “red” taint could never be used against them.
Up until 2000, there was no rhyme or reason for who got which of the two colors. You could flip from channel to channel and see the GOP states go blue one place and red the next.
After 2000, we have become universally “red.” So much for Fox News being different.
