Publishing brands Penguin and Dorling Kindersley, both part of the Penguin Group, recently completed a project to relaunch their websites and improve interaction and navigation for users.
The revamp was pretty far reaching - the team took a user-centred approach, with extensive usability testing and planning, and found new ways to think about marketing books via the site.
The group is also set to launch new sites to increase its engagement with customers - one is a youth-oriented site called spinebreakers.co.uk, which is employing teenagers in its development.
Here, Penguin and DK's online development manager Jeanette Angell speaks about the reasons behind the project and the techniques it used.
Club Penguin, the children's virtual world, has been acquired by Disney in a deal worth up to $700m (£344.5m).
The media giant will pay $350m upfront for the fast growing site - which had reportedly been a $500m target for Sony.
Children's TV network Nickelodeon is to increase its investment in online games for kids - what is fast becoming a valuable market online.
The firm says it will invest $100m (£49m) over the next two years in improving and adding to its current online offering, including new subscription services, multiplayer games and virtual worlds.
