magnitizm. If you have a magnitized cable that goes from... let's say your gameing system into you vcr. And you, by accident, put the cable into your tv's cable slot, it would realy mess up your tv....
it dependsif it's Spongebob then it rots your brain, but if its like the Discovery Channel and actually teaches you something (cheetahs are the fastest animal on Earth) than that's ok and your brain...
The bad effects if television is that,.
it is very addicting and changes your behaviour..
it also is a bad influence in some ways like the nudity and the bad language..
