Facebook’s press event last week focused entirely on adding video to Instagram, despite previous rumours that it might also be launching a news-reader service. Now those rumours have re-emerged with the most credible source yet: the Wall Street Journal. It claims Facebook has been working for more than a year on a new product codenamed ‘Reader’, which “displays content from Facebook users and publishers in a new visual format tailored for mobile devices” with a particular focus on news content. “Recent versions of Reader resemble Flipboard Inc., a smartphone and tablet app that aggregates stories from multiple sources and lets users swipe to flip through articles,” claims the piece, which suggests Facebook CEO Mark Zuckerberg has been closely involved with the development. News may be the focus, but we can imagine several ways music might fit in neatly with Reader when (or if) it gets released. For example, updates from artist pages being presented in their own section, and/or integration of Facebook-friendly streaming music services like Spotify and Rdio to play tracks.
