I wonder if Radio Shack used annealing ovens on "Eye of the Storm" plasma displays? If those displays use 1-atmosphere argon/helium/xenon mixture, then perhaps the outgassing from the glass has little effect since the outgas volume is tiny when compared to the gas that's in the globe.
Cheap plasma globes never seem to last too long :-( They stop working after a year or two. In the light of this discussion, I bet it's due to outgassing.
