Time Magazine, July 3, 1995: 
That’s what I’m trying to determine. If the iPad access is actually any easier than it was on the computer. Logically, yes, more portable, but not sure if that actually means easier access.
We also have better parental controls on tablet devices now that we didn’t even have back in those days.
Then I would say it's dependent on the parents to set up good parental controls
