“Public television is the literate alternative to commercial television.” This is how an article titled, “Metaphoricaltypography” begins, in an issue of U&lc from 1975. In it Lubalin, (editor of U&lc and its designer), describes the approach of his studio to making animated titles for PBS done sometime after 1971.
