Default Since when is 26" now 25"

I thought i would switch over the old 26 x 1-3/8 tires on my Circa 1970 3 speed touring bike for newer 26 x 1-1/2 tires from a mountain bike. I tried and tried, but no go. Then I measured the wheel diameters, old is 24", new is 23". And then the tire diameter, Old is 26" and new is 25".
So, If I go purchase a new 26" tire must it be a 1-3/8" width? And will it fit? What's up with that. Are all 26" bikes today really 25"?
