excerpts:
MRI brain scans showed children who spent the most hours in front of the box had greater amounts of grey matter in regions around the frontopolar cortex - the area at the front of the frontal lobe.

But this increased volume was a negative thing as it was linked with lower verbal intelligence, said the authors, from Tohoku University in the city of Sendai.

‘These areas show developmental cortical thinning during development, and children with superior IQs show the most vigorous cortical thinning in this area,’ the team wrote.

They highlighted the fact that unlike learning a musical instrument, for example, programmes we watch on TV ‘do not necessarily advance to a higher level, speed up or vary’.

‘When this type of increase in level of experience does not occur with increasing experience, there is less of an effect on cognitive functioning,’ they wrote.
 
Yes... and now every two year old in the country has a tablet. I have a sense we're about to have a generation of people with overdeveloped motor skills.
 
I would say that the garbage on the tv is harming children more than the act of watching a tv

Yes, garbage/propaganda is horrid, but TV is dangerous for all young children/babies. The young child is trained to become a lazy passive thinker because any kind of stimulating TV sound/picture requires no active thought whatsoever as the brain develops and then craves the EZ stimulation. No hard/deep thinking is required. For millions of people, the resulting conditioned thought process is usually passive.

Even a dancing test pattern and engaging music 24x7 will completely smother early childhood curiosity and create slow zombies!

Feed 'em discovery/science/history/shopping channel TV programming and you still get non-critical thinking, passive brain encyclopedic zombies. Some are very quick when regurgitating facts and tidbits of info, but critical thinking, reading and creativity are more rare.
