Installing this extension will block all websites that Rupert Murdoch controls.
This app was released in May 2014 and makes the boastful claim to block all News Corp controlled websites. There have been no updates but the comments on the Chrome Store all rate 5 stars and couldn't be happier with it.
I don't have a copy of Chrome running on any of my PCs, so I haven't tested but I am endeavoring to have a play with it soon. If anyone can beat me to this, please comment below on your experiences.
*Note: Google Chrome Web Store doesn't as yet support Android
