When Dr. Bob Wagstaff invented the Orabrush tongue cleaner, he tried all the traditional business strategies to sell his product. He invested $40,000 into a TV infomercial, approached retail shops to carry the Orabrush in stores and offered to sell his patent to other oral hygiene companies. None of it worked. The infomercial yielded only 100 orders, and people walked past the product in stores without a second glance.
As a final attempt to get his business off the ground, Dr. Wagstaff took the advice of Jeffrey Harmon, a local college student, and started marketing the tongue cleaners on YouTube. With a $500 budget, they produced and posted their first video introducing the Orabrush and offering the product for purchase online.
