This TED talk by Charles Leadbeater deals with some of the issues around innovation. He talks about radical innovations and their uncertain applications versus incremental innovation. He also gives examples about how our perception of creativity has shifted from lone geniuses to collaborative, passionate user based innovation. Also, the move from closed resources to open-source material. This trend is similar to the shifting approach from traditional design to a human-centred approach including participatory-design and co-design.
