When Dyson released its bladeless fan in 2009, customers were taken aback. The Telegraph then noted that, once more, Japan had advanced a few years ahead of us, having created the Dyson bladeless fan as early as 1981. Many imitation companies hopped on the bandwagon once Dyson re-released the fans.
