This is another popular method to grow in affiliate marketing. For me, the best way to make the most out of affiliate marketing opportunities is to have a blog. Learn how to start a blog here.
While any “regular” job requires you to be at work to make money, affiliate marketing offers you the ability to make money while you sleep. By investing an initial amount of time into a campaign, you will see continuous returns on that time as consumers purchase the product over the following days and weeks. You receive money for your work long after you’ve finished it. Even when you’re not in front of your computer, your marketing skills will be earning you a steady flow of income.
In the United States, Federal Communications Commission (FCC) regulations limit the number of network-owned stations as a percentage of total national market reach. As such, networks tend to have O&Os only in the largest media markets (such as New York City and Los Angeles), and rely on affiliates to carry their programming in other markets. However, even the largest markets may have network affiliates in lieu of O&Os. For instance, Tribune Broadcasting's WPIX serves as the New York City affiliate of The CW, which does not have an O&O in that market. On the other hand, several other television stations in the same market – WABC-TV (ABC), WCBS-TV (CBS), WNBC (NBC), WNJU (Telemundo), WNYW (Fox), WWOR-TV (MyNetworkTV), WPXN-TV (Ion Television), WXTV-DT (Univision) and WFUT-DT (UniMás) – are O&Os.
