Why are wifi, cell phone, radio and satellite television waves not constantly running into each other?

I'm know interference happens, but given the growing number of items that put out waves, even of the same frequency, how come we don't see more instances of waves colliding and breaking signal?

Is this possible, or am I way off?

Electromagnetic waves don't collide. An EM wave can go through another one as if it wasn't there. It's due to the linearity of the equations of electromagnetism: if you add two solutions, it's still a solution. They just superpose, and then you can filter the waves you want according to their frequency for example.
