In the case of news, this practice, in my view, results in inefficient communication. I question how much of televisions' nightly news effort is really absorbable and understandable. Much of it is what has been aptly described as "machine gunning with scraps." I think its technique fights coherence. I think it tends to make things ultimately boring and dismissable (unless they are accompanied by horrifying pictures) because almost anything is boring and dismissable if you know almost nothing about it.
