How come we hear NOTHING about the Soap Box Derby anymore?

As a kid, it used to be on ABC's Wide World Of Sports and often on the news. I have often wondered if cheating and corruptness hurt?? I recall hearing stories about Dads placing large magnets in the nosees of the cars so when the metal gate dropped, it sorta slung the car forward. That was in the late 80s / early 90s...and around the time I stopped hearing anything about it. I just had to Google it to see if it even existed. It does.
