No longer does an Electrolux Aquaguard reseller for instance, have to employ mechanics to service the water purifiers when simple product training (with the market development funds provided by the manufacturer) avoids this extra expense and provides coverage in areas that could not be physically reached prior, all with zero impact on his own payroll.
That inspired me to try other new products, like the first wireless telephones, the first telephone answering machines, the first air purifiers, and eventually this led to a full color catalog of new technology products, and later, 200 retail stores.
In this way, things like rocket engines, satellites, Mars-exploring rovers, space suits, and water purifiers on the International Space Station become part of everyday life on Earth.
