More than any other I notice public television sets are set to CNN, at least in the USA. For instance, almost every airport,(sometimes sports are on with ESPN but rarer) has the old CNN.
Is this just human herd behavior that at one point everyone just sets it to CNN when they install a new television set? You would think they would have so many stations to choose from though, and it is not really a fashion that one wants to conform to. Is CNN really that spectacular?
