Everyone, literally, everyone wants this.
Commercials are recorded to play on any number of channels...different channels are broadcast at different volumes.
So unless the broadcasters themselves regulate the volume of their programming and the commercial to be at the same level, the commercial can often be much louder than the programming on that channel at that time.
Contrary to popular belief, advertisers aren't doing this on purpose...they want to grab and hold your attention, and if you're leaping for the remote and hitting the mute button they can't do either.
So maybe it's not the will of the people...it's Big Madison avenue lobbying the FCC
