Television is the most popular medium. Explain it with its reason.With competition from Netflix and a host of new digital video providers, the television industry has undergone seismic changes over the last five years. But one thing has remained constant: TV is still by far the most effective advertising medium.
That's the finding of a new study Turner Broadcasting and Horizon Media partnered on with marketing-analytics company MarketShare, which meta-analyzed thousands of marketing optimizations used by major advertisers from 2009 to 2014.
MarketShare's analysis found that TV advertising effectiveness has remained steady during that time period and outperforms digital and offline channels at driving key performance metrics like sales and new accounts. The study also showed that networks' premium digital video delivered higher than average returns when compared with short-form video content from nonpremium publishers.
