Did Arcades ever operate 24 hours a day?

I can see how a CRT would last a lot longer being used in a " vector" format.

Think about it. Over 90% of the screen...and therefore cathode..goes UNUSED at any given time. SO wear would be seriously decreased . Sure "burn " would be a real problem-- ( and WAS--even 30 or so years ago on games I played like centipede, ) even more so than a normal raster display which has a "background" glow, and is always lit to some degree. But the cathodes and phospor as a whole would seem to last a LOT longer. I doubt many games had the tubes replaced for burns unless it got to be so bad they were not useable.

In FACT..I would hazard to say...that LCD panels would last LESS time in a vector display than a CRT , given the BL has to be on ALL the time--other than modulated BL ones--(and I doubt any arcade games use them).. and so they would wear out quicker that way. Not too mention...there would be a bit of "glow through" on ANY LCD used in a vector display from said BL..
