Beginning September 13th you will be able to watch your favorite BBC shows online, all the time. In the past, the BBC would post shows to the iPlayer and keep them up for only 7 days.

The new format will use series stacking, which basically means as each new episode becomes available, it will stack on top of old episodes. All episodes will remain available online so you will have the opportunity to watch entire series in one sitting or, just catch up on a few weeks of missed viewing.

According to the BBC press office, you will be able to catch up on a maximum of 13 episodes. It doesn't state if that's in one sitting or for one series or on the iPlayer overall though. Seems like an important detail to include.

iPlayer use for television shows is limited to those connecting from the UK, though radio programs are available to everyone.
