Why would Apple even bother trying to patent this? Other people have already created tools that allow you to do it.
This patent is moot.
I think it's a great idea. But If there are other tools out there that do the same I would be interested. Would you be kind enough to point me in the direction of a tool that allows me to selectively mute individual sites. There are several sites I would like to mute but don't want to un mute each time I go to YouTube or hulu.
