The Digital Zone at the annual London Book Fair - the UK's largest book event which was held this week - has been steadily growing over recent years.
In the space of five years, digital authors and the companies representing them have gone from a handful of exhibitors' stalls, to close to 70. And their three dedicated theatres hosting live discussions have attracted large crowds over the three-day event.
This has mirrored the steady rise of ebook market share in the UK, which currently stands at about 10%.
BBC News caught up with a selection of people involved in e-publishing attending the event, to find out why they came, and what they think the rise of the ebook means for its paper counterpart.
