Back when a Finnish radio channel got a website, they had an infuriating ad where they played Surfin' USA by the Beach Boys and invited everyone to come surf on their site, and read out their URL: aitch tee tee pee colon slash slash double-u double-u double-u... I suppose browsers started filling in the URL scheme pretty early, because I remember somebody arguing that you shouldn't leave it out, it could well be ftp or gopher or who knows what they invent next.

Slashdot was reputedly named slashdot to make spelling out the URL humorously awkward: h t t p colon slash slash slash dot dot com.
