How Did Goal Celebrations Become A Thing In Football?

Many decades ago, the way football used to be was: a player puts
the ball in the back of the net, turns, and quickly starts
running towards the centre of the pitch for kickoff. The best you
can get is a couple of hands in the air, a couple of jumps, and
it’s back to it.  


There was none of these running to a corner of the pitch or to a
camera for some extravagant displays.   


So, the question now is; how did we go from that to this? How did
we go from just modest expressions of joy after scoring to
routine celebrations, some even now having names and soundtracks?
