I saw this little tidbit from Wikipedia.
`5 year cycle
The yo-yo tends to go through 5 year cycles of popularity. Once the popularity of yo-yo’s amongst kids wanes, yo-yo companies go on a marketing campaign every 5 years to bring back yo-yo’s into the public consciousness, which is usually a successful tactic.`
So I was wondering, when was the last yo-yo campaign? Does anyone know?
