The proliferation of cable television channels and special-interest television programming in recent years has created plentiful targeting opportunities for business owners with niche products and services to target local shoppers based on special interests. You can reach your local target audiences on cable TV by using popular channels such as ESPN, Discovery, TNT, CNN and HGN, to name just a few. Most local cable companies reserve low-price advertising slots to sell to local advertisers. For instance, if you owned a sporting goods store, ESPN would be an ideal cable channel on which to place your commercials. Moreover, most cable companies will actually produce the commercials for you.
