I have noticed that the tv is always on at daycare. I love our at home providers, but everytime I drop our child off, the tv is on and she becomes fixed to the screen.
I agree with the fact that to much TV is perjudicial but maybe it is not on all day but only at the time the babies are coming in. Even in that case it depends on the program they are watching. Make sure to talk to the person in charge to see what their ideas are on this respect and to let them know your opinion.
I like my grandson (30 month old) viewing Ni hao Kai Lan or Diego or Dora that not only mention other languages but teach them many things like 'sharing', 'controlling emotions', 'helping others'. Nevertheless it is important to be with him in order to comment on what we are seeing and not leave the TV do the work. And control the daily exposure time, balance with playing with puzzles, runnig, hide and seek, singing, dancing, reading, building blocks etc etc.
