Marketing. At least in its current form.
The world needs people being paid to manipulate consumers with biased information like a democracy need vote riggers. If they'd all work on a (forced) "most objective and neutral" criteria for description, then it'd be fine to spread the word wide and far, but the current breed is about as objective and informative as a North Korean propaganda video. Which is probably where they had their internship during their studies of communication.
