There has been a huge growth in online news and a shift away from mass media towards social media. This has caused a crisis in professional journalism due to declining revenues and shifting audience attention. Younger audiences prefer short, concise news from blogs and social media rather than mainstream news sources. A study identified three types of online news users - convenience users who prefer short news, loyal users who remain with particular brands, and customizers who curate their own news sources. Facebook is a major source of news for younger Australians.
