We have had a lot of interest in IPTV over the last week, with the IPTV World Forum in London and the CeBIT trade show in Hannover. Meanwhile there is increasing interest in mobile television. The definition of interactive television is changing, and that does not just mean high-definition television. At informitv we have always had a wider view of interactive television services that has been welcomed by our clients and readers. Please let us know if there are particular topics you would like to read more about on informitv. As always, we welcome your feedback.
