direct response marketing, infomercial advertising If you have a product that is really useful for people, you could try direct response marketing to sell it. Direct response marketing is a good way to demonstrate a product and get information out to people. If your product lends itself to television, this is a tried and true way to sell something. Infomercial advertising is used to sell tangible and intangible products. Real estate, investment clubs, kitchen products, car add-ons, nutritional supplements-basically you name it-is sold this way. Some people use television infomercials to promote a product, and others use booths at flea markets or art shows to demonstrate their products. The internet is also becoming an easy and far less expensive way of selling products, compared to television advertising. There are just the production costs, and the low monthly internet fees to put it on a web site so that lots of people can view it. Some people advertise their products on free sites like Craigslist. They put up an ad in the appropriate category, and put in the link to the site.
