I have just found this video back from the 90's (1994, to be more specific) about naturism in Brazil. It's very informative (10 minutes), specially because in that time, general population wasn't aware of naturism (well, the situation has not changed so much in this aspect).
Things worth notice in the video:
1. How naturism in Brazil evolved since then (great for comparison)
2. How there were no censorship, nor "blurrring" the nudity in the video. Such thing would not happen nowadays in Brazilian television for sure
3. Giant walkie-talkies! Oh, the 90's! How time flies!
