was to judge whether or not the ball

touched the net when the players served.
The net-cord judge has now been replaced
by a sensor which is attached to the
centre of the net and sends a signal
directly to the umpires chair via an
earpiece. The umpire then makes the call
of ‘let’. This goes against the trend of
having extra officials (such as the fourth
official in football) as tennis has actually
reduced the number of officials through
the use of technology.
The Wimbledon Tennis Championships
also used to use a system called ‘Cyclops’
which judged whether or not serves were
