Multitasking TVs at the airport

Stuck at the airport in Austin the other day, I couldn't help being fascinated by the three TVs in a café. Each of them was on a different program (news + sport 1 + sport 2) and the sounds of each channel was mixed with the background noise of the place (+ music). The different device sit there all day and broadcast their message continuously.

This situation did not prevent the avid users to follow what was going on at the time, especially because of the weird subtitles appearing right in the middle of the screen (with a certain delay):

"... at what's trending on the interwebs and social me..." says the CNN person.

Why do I blog this? Fascination towards the deluge of information appearing at 5am in a café, and by the "interface" tricks to let people grasp small bits from this.
