Since I was a kid, when the first moon landings occurred, barely aware of it going on under my nose, I have since paid scant attention to the fact that radio signals have been moving away from us at speed for a long time. They have travelled something like 85 light years, further than Aldebaran, as far as Regulus.

So it is now possible, though probably statistically unlikely, that aliens are sitting in front of their TV's watching our broadcasts, not yet having broadcast for long enough for us to watch theirs.

That would be cool. Can't wait to see what kind of programs they make... and will their programming be influenced by ours?
