In airports, the people in charge of the TVs get PAID to put on CNN. It’s that simple. CNN has contracts with most major airports.

When I travel, you see CNN on the TVs. However, unless there is a major breaking story, or weather event, people generally are not paying attention.
1) The CNN airport feed constantly rehashes the same stuff
2) People are focused either getting from point A to point B or their phones.
