Powerboard
A Great Invention To Help Spread The Load Of Home Appliances
In 1972 an electrician named Frank Bannigan built himself a four-outlet power board to help with his work. He decided that other people would find a power board useful and started to manufacture them, forming a company called ‘Kambrook’. Soon his company was selling thousands of them. However, Bannigan did not patent his invention. He lost millions of dollars in potential earnings when others copied his idea.
