I'll look for something on the Internet but I see the ghost stuff on TV not on the internet.
Don't believe anything you hear, and only half of what you see.
Also, I'm not sure what television show you're watching but it's most likely faked. They can convince people to think "OMG WE FOUND GHOSTS" whether or not they found ghosts or not. So, people keep on watching the television show/buy their shows on DVD. It's all in the name of profit.
But I'm just being overally cynical and a pessimist. Of course the TV doesn't lie to us.
