Thompson outlines his views in a recent speech that suggests that the BBC needs to completely rethink itself around the Internet.
“On-demand changes everything. It means we need to rethink the way we conceive, commission, produce, package and distribute our content. This isn’t about new services, it’s about doing what we already do differently.
“The BBC should no longer think of itself as a broadcaster of TV and radio and some new media on the side. We should aim to deliver public service content to our audiences in whatever media and on whatever device makes sense for them, whether they are at home or on the move.”
