Wal-Mart is selling the world's first DVD player that can seamlessly skip over violence, swearing, nudity and other potentially offensive movie content. The $79 unit features technology by ClearPlay and is manufactured by Thomson Inc. under its RCA brand.
This is an amazing example, of how the market works. Although items such as this have been around for a while, this seems to be the most advanced one I have seen (it uses pre created filters to filter the smut). Their is a market for clean, non-violent movies. So the market fills that hole.
Welcome to America.
