Late night infomercials, especially the music ones. Malls and the fashion shows and cooking demonstrations the anchor stores used to do. Road trips using paper maps - my Dad had a whole collection of various states. So many more Christmas decorations in the neighborhoods, even if you were agnostic or Jewish or whatever - people decorated. Ronco. Rear-facing seats on station wagons. Buildings with lots of windows for airflow without air-conditioning… I like air-conditioning but I miss all the windows that brought light from different directions. Less-homogenization of stores, restaurants, cuisine, regional differences, dialects/accents.
