Over 80% of football fans are in favour of it and it's going to be trialed at the 2007 FIFA World Club Championship - so will goal line technology be here to stay? I thought I'd do a bit of research on this and share that here.
Naturally, as most games of football only see an average of 2 or 3 goals, one more or one less makes all the difference. There are times when it's too close to call and, whatever the decision, it leaves one team and their fans enraged. On the odd occasion, a clear goal is missed by only one person - the referee. Let's be honest, refs need all the help they can get.
How it works:
Sensors are placed inside the goal posts (or at least inline with the posts) and they determine where the ball is. They look for a chip inside the special "smartball", which is a football, except that its total weight, properties in the air, rate of spin, etc are no different to an ordinary football. The chip must also remain in the centre of the ball despite all the knocks it receives. The sensors look for the chip about once every millisecond and when a ball has crossed the line, the referee's specially made watch vibrates and/or makes a buzzing sound (or if I was to design it, dispenses a reasonably high voltage electric shock).
So let's bring it on! We've all had enough of the type of bitterness exemplified by the German football fans over World Cup '66.
