Google Now can block publishers you don't read

You can already tell Google Now to stop showing you stories on certain subjects, such as an annoying political candidate or a rival sports team. But what if you want to purge an entire site from that long list of info cards? You're about to get that chance. Some users have noticed that Google Now is giving them an option to block entire publishers, regardless of content. If you're irked by a tabloid cluttering your feed, you can banish it forever.
