Petitions can be a very powerful tool. If enough of the target audience signs one, things can happen. That is exactly what some people are trying to do with these following petitions. They are designed to show studios that they want to view their libraries of titles on HD DVDs. If these reach enough people, they might just do the trick. We do have to note that HDBeat is not taking any specific side on this war though (I have however), but if this is your kind of thing, you might want to go sign your John Hancock - digitally that is.
