Thank you to the San Jose Mercury News for this wonderful link--to a 1930s newspaper ad promoting a set of National Union Radio Tubes as a gift for the whole family. Over on Vintage Ad Browser, I also liked the 1968 ministereo and the 1977 Tummy Television--remarkably prescient; it looks like how my family watches TV today on a laptop.
