Thanx for the replies everyone! I started to feel like I must be the only parent that supervises what my kids watch/read/play. My SIL allows her 4-year old to watch CSI with them!
We pretty much do what everyone here describes. I even sensor the children channels too, not allowing them to watch anything without me giving the go ahead first. I find some cartoons very inappropriate at times and don't like that level of violence for 3 or 4 year olds. My 12-year old can now watch most of it without his siblings.
Alice, I also find it difficult to put rules in place for when they're at grandma's. We did ask them to please not watch news while the kids are around, because it was upsetting them. FIL thinks we're overprotective.

We live in a very violent country though, and I'd hate for them to feel unsafe when there's so much of it on the news.
I do allow my 12-year old now to play games that's listed until 13. But 16 and 18 rated we still keep away from him. My 9 and 5-year old can only play age appropriate.
I just have a problem with books. My 12-year old reads thick books now, that I can't just quickly page through (especially difficult on the kindle). I'm not sure what's appropriate and what not for him. He started the swords of truth series, but I stopped it after book 2, because it seems to get violent and sexual. He's now busy with the Eragon series, and before these, he read the harry potter series. But he really want to finish the swords of truth.
Vickie, I also used to change the story books' wording, when there was sadness or violence I didn't like. Then, they started to read themselves and exclaimed how much different the stories suddenly are to how they knew it.
