I think the tv broadcasters switched to the Bullens Road after the completion of the main stand in 1971. Almost all of the tv material from Goodison up to then including the 1966 World Cup was filmed from the old main stand.
As AB says there's quite a bit of internal footage shot from the Main Stand well into the 80's.
In the days before near blanket live tv coverage of football, in the 1980s the club used to record every home game and sell VHS copies of the full 90 minutes of every home game.
