West Germany have always claimed Hurst's second goal in England's 4-2 win in the 1966 final did not cross the line after it bounced down off the crossbar.
TV replays do seem to back up that theory, yet a definitive answer will never be established.
Now, though, referees should be certain of making the right call, with the system in use for the first time in Sunday's Community Shield encounter between Manchester United and Wigan at Wembley.
And, speaking at the 2013 FA Community Awards presented by McDonald's, Hurst admitted the move has not come a moment too soon.
"If we had this system 50 years ago, it would have shown quite clearly the ball was at least a foot over the line," he said.
"Germany have been arguing the toss ever since but I will never tire of talking about it. They can't take it away now anyway. It is in the book.
"But I certainly welcome the move. We tiptoed round it until that Frank Lampard 'goal' in South Africa. I have always believed in it but that was the tipping point."
Lampard thought he had scored what would have been an equaliser in the 2010 World Cup last-16 clash with Germany in Bloemfontein.
However, none of the officials spotted the ball bounced a couple of feet over the line and allowed play to go on, with England subsequently losing 4-1.
