Digiday: Last November, CBS News launched CBSN, a free, ad-supported streaming news network available online, on mobile and connected TV. To get people to watch it, CBS News pulls from its well of viewership data. For instance, CBSN viewers are currently very interested in next year’s presidential election and are eager to follow each debate whether CBS is broadcasting that debate or not. In fact, even if CBS is not hosting a debate, CBSN still sees noticeable spikes in traffic to its debate coverage.
