BBC iTalk was an idea created from a D&AD brief, to get users to engage with BBC content more.
If there was a show that created a lot of chatter and discussion, there would be a chat show off the back of that show. iTalk was to be built into iPlayer and the audience at home would be able to participate in the chat show. They would submit their questions in audio, video on a typed message format. This was all before Twitter and hashtags became widely used as a means of audience participation.
Not only was iPlayer only available on a desktop platform, I thought about pushing the idea to work on tablet as well, before it was the norm.
I also suggested that the user would be able to sign up to show their interest in certain types of genres and be given notifications when relevant shows were coming up.
