People that are parents today grew up with the big boxy CRT TV's that, by virtue of being cube shaped, were pretty stable and had a low center of gravity.
Now TV's are thin and ones not mounted on walls usually sit on a stand that has a footprint smaller than an 8 1/2 by 11 piece of paper. Combined with a higher center of gravity, modern TV's are much more prone to tipping over. And as we all know, small kids running around will trip and hit furniture, rocking the TV enough to tip it over.
One other problem is that for people that live in apartments, terms of the lease usually prohibit driving nails or screws into the wall. That means that no anchor strap can be attached to the TV to prevent it from tipping over.
As was mentioned, I'm guessing this is less of an issue with the advent of flat screen TVs, but I have my flat screen fastened to my TV stand, just in case.
Also, flatscreens actually make the problem worse; with less of a base, they're easier to tip over.
