I'm really rather torn on this one.
First, the report itself:
1. They advocate 1-2 hours of
screen time. This
includes video games, TV, movies, etc. They are at least consistent on this point.
2. Their recommendations "based upon the AAP" (American Academy of Pediatrics) is a bit misleading - the AAP recommends that children ages 2 and up be limited to 1-2 hours of TV, but they don't seem to provide an upper limit for this guideline.
3. They somehow managed to get their DSM numbers wrong. The DSM-V is currently being written - not the DSM-IV, which has been published since 1994 (TR / text revision was published in 2000).
Tossing the report aside for now, there certainly is a thing called "TV / Internet / movie" "addiction." For the sake of brevity (ha) let's refer to it as "media addiction" and also clarify a few things.
1. We are talking about psychological addiction, not physical addiction.
2. As it is psychological, there is a lot of other factors that can influence whether or not someone is addicted. Personality mostly, though neurological can certainly play a part as well.
3. What constitutes an "addiction / overuse" for some may not necessarily be an "addiction / overuse" for others, depending upon responsibilities and how the individual manages their time.
4. Psychological addictions typically require several factors before a psychologist would diagnose an individual as having an addiction:
1. General detriment - social, economic, etc (generally mental).
2. Neglecting responsibilities (work, school, etc).
3. Taking risks (social, economic, etc) in order to engage in the activity more (personal relationship issues).
4. Acknowledgement by the individual that the activity is harmful to them (not always necessary)
(This is not a exhaustive list, nor is it necessarily accurate)
On one hand, I agree with the science - there can be detrimental effects to staring at a TV / computer screen for an excessive period of time each day (physically and mentally - everybody here have 20/20 vision without correction?

). On the other hand, the recommendations perhaps seem a little extreme for anyone over the age of 10-13, who will increasingly be using computers and the Internet.
And this all coming from a graduate student who is getting his Ph.D over the Internet and spends 8+ hours a day at a computer.
