We are getting a crash course in the US election system, but one thing I don't get is why there is so much emphasis being placed on TV networks calling a state.

Anyone know?

Just heard that Biden might actually claim victory IF / WHEN CNN calls Pennsylvania blue. Given that a TV network's call is not official, why is it used as the indicator? Likewise, Trump cracked the wobblies when Fox called Arizona blue. Why is it such a big deal if its not official?
