I don't have a TV license but went on I player to see what was currently on. It mentioned that you can buy programs from the BBC shop. As I have never used this shop I just have a few questions about it. Do I need to download the programs if I buy it ? I don't have enough space on my iPad to download many more things so can I just stream what I buy. How long can I watch the programs I buy for? Is it just TV or does the BBC shop sell other things as well?
