What was the first Lego tie-in film or television production?

Question

Nowadays, it's pretty common for TV shows and films to be released by film studios in agreement with The LEGO Group and tying in to current LEGO set themes - famous examples include the recent films (The LEGO Movie and The LEGO Movie 2: The Second Part), LEGO Star Wars: The Yoda Chronicles, the Legends of Chima TV series, and Ninjago: Masters of Spinjitsu, all of which were released after 2010.

What is the earliest television or film production that was officially tied in with a LEGO set or theme or with LEGO bricks in general? The earliest that I was able to find was Edward and Friends from 1987 that showcased the Fabuland theme, but LEGO was already decades old by then. Was there anything before that?

Answer 1

I think you already answered your own question: The earliest Lego television production is Edward and Friends from 1987 that showcased the Fabuland theme.

From the Wikipedia page:

It was Lego's first foray into animation and television in general.
