I think it depends on one's definition of "mainstream news". Traditionally and I think most commonly understood, it means news that is published in widely circulated newspapers, and on accessible television. The times are, of course, a changing. Almost all newspapers in the UK at least have, today a really low circulation number. They are widely available, but hardly anyone buys them anymore. The Guardian, for example only sells 156 thousand copies.
