There are two basic markets you can sell to: consumer and business. These divisions are fairly obvious. For example, if you're selling women’s clothing from a retail store, your target market is consumers; if you're selling office supplies, your target market is businesses (this is referred to as “B2B” sales). In some cases—for example, if you run a printing business—you may be marketing to both businesses and individuals.
With few exceptions, such as American Idol, the Super Bowl and the Olympics, it is not common for a substantial audience to watch a program at once. Still, networks do target particular demographics. Lifetime targets women and MTV targets youth. Sports channels, for example, STAR Sports, ESPN, STAR Cricket, and Fox Sports, target the niche market of sports enthusiasts.
