[Dragonball / Z] How come everyone forgot about Goku and his actions in Dragonball?

Like, why does everyone think energy is a trick by the time Hercule is famous? He won the World Tournament no more than 10 years after Goku defeated Piccolo and they both used powerful energy techniques, I can't recall if it was televised. Plus old King Piccolo was the first major villain to have attacks that could threaten a city and no one except the announcer dude remembered by the Buu Saga. Videl said she had to look Goku up. I thought Master Roshi and Master Crane were world famous. Makes no sense.

The World Tournaments were not at the forefront of mainstream culture. Martial artists knew who Crane and Roshi were and who had won recent tournaments, but the average person, not so much. Mr Satan was famous not because he won the tournament, but because he's a skilled self promoter. His championship was the springboard he used, but he's far better known than other winners.

For an example for our world, I'd hold up the governator, Arnold Schwarzenegger. He was able to use his Mr Universe championship as a launching pad to become famous. You could go anywhere in the world and find people who know him today, but how many other Mr. Universe winners could the average person name? Schwarzenegger was a hustler (in the best sense of the term) and able to use his victory as a selling point, but it's not what made him a household name on its own.
