This is a highly startling conclusion you've come to. Flip through the channels that are available to the average household today, and you'll come across plenty more skin being flaunted and various other types of titillation than by performing the same experiment in 1978. That I can guarantee you.
The same, by the way, goes for walking down the street and observing people.
I don't think that I'd agree with the second part of that, the more skin on the street part.
I remember virtually none of the college girls wore bras in Bolder in 1980. The thin skin tight short shorts and body suits of that time have given way to ultra low rider jeans, but in my recollection there were more halter and tube tops, underwear outerware, translucents and low necklines given peep shows in the 80s and early 90s. Even male attire was designed to show off muscles and highlight "packages". Today baggy everything works, or it that on the way out as well?"
