Pull tabs on beverage cans.
Returnable bottles. (TRUE recycling)
Transistor radios.
TV stations going off the air every night.
Stores being closed on Sunday.
At sign of they would play the National Anthem, then the test signal with the image of an Indian Head similar to the one on a Buffalo nickel.
Also, on pull tabs, I remember my dad having to use a can opener to puncture those triangular openings on his beer cans or on us kids Hi-C cans.
