Today has seen the launch of BBC's on-demand TV service, BBC iPlayer which lets you download a wide range of BBC television programmes for free from the last seven days.

The programmes you choose to download are stored in your BBC iPlayer Library on your computer for up to 30 days (once you download the iPlayer). You then have up to seven days to watch them. Once you download them you don't have to be on the internet to watch them when it suits you.

The viewer is now taking control as they start to dictate what they watch and when they watch it.
