This document compares different advertising mediums and their costs and benefits. Television advertising has wide reach but high costs and declining viewership. Newspaper readership is decreasing among younger demographics and has high frequency costs. Billboards have limited reach but are cheaper than other options. Internet advertising allows direct response, one-to-one marketing, and long-term cost reductions at a much lower cost than other mediums. Social media marketing can boost website traffic, likes, shares and followers but companies must understand how to effectively leverage these platforms.
