The creator of Downton Abbey Lord Fellowes is publishing his next work, Belgravia, weekly in 11 online episodes, in an episodic fashion similar to how Charles Dickens published many of his novels. Lord Fellowes and Ashleigh Gardner, head of content at episodic/interactive publisher Wattpad, discussed this old-fashioned and yet very modern new format. (Image: Lord Fellowes and Ashleigh Gardner.
