Context:
In 1962, graphic designer Paul Rand redesigned the ABC logo into its best-known (and current) form, with the lowercase letters "abc" enclosed in a single black circle. The new logo debuted on-air for ABC's promos at the start of the 1963–64 season. The letters are strongly reminiscent of the Bauhaus typeface designed by Herbert Bayer in the 1920s, but also share similarities with several other fonts, such as ITC Avant Garde and Horatio, and most closely resembling Chalet. The logo's simplicity made it easier to redesign and duplicate, which conferred a benefit for ABC (mostly before the advent of computer graphics).

Question:
When did Paul Rand's iconic ABC logo first debut?

1963–64 season
