A lot of color tv sets, and likely monitors, have a built in degaussing 
coil.  They are physically placed around the front of the CRT, and 
connected to the AC line via a thermistor or something.  So when the set 
is turned on the first time, it is automatically degaused.  Yet it doesnt' 
come into play if you turn off the tv set and then rapidly back on.

Yes, early tv sets didn't have degaussers, but it's been at least thirty 
years, surely longer, that they've been standard.
