I've noticed a disturbing trend on TV of late . . . text on the screen (often in annoying graphic layouts, but that's another rant for another day) accompanied by a voice-over or talking head who is speaking the words as they appear on the screen. Not summarizing. Not paraphrasing. Saying EXACTLY what is on the screen.
Attention producers of my local news promos and national prime time TV teasers: if I can read it, I don't need to hear it . . . and if I can hear it, I don't need to read it. This applies to presentations, and it should apply to television as well. If I wanna read my TV, I'll turn on the closed captioning.
