used to trace those who were evading TV Licensing whilst using the iPlayer; Andrew Scott, launch director of the ongoing initiative, stated that the BBC might use account email addresses, along with existing methods, to help identify iPlayer users who did not hold a television licence. However, he repeatedly said that the account system was primarily intended to provide personalization features across BBC properties, such as content recommendations on the iPlayer, and the ability to continue watching a programme on one device from where it was left off on another. Computer platforms 'iPlayer 1.0' Download service One of the key features of the original iPlayer download service was the use of peer-to-peer (P2P) technology to enable the distribution of large video files (i.e. TV programmes) to scale effectively. Once downloaded, the content was only playable within the iPlayer itself or Windows Media Player 10 or 11, and subject to digital rights management. In December 2008, the BBC moved to an Adobe AIR-based client that downloaded content via HTTP rather than P2P. The new system replaced the Windows DRM system with Adobe's own. DRM software prevents it being directly copied to another medium (e.g. another computer or CD-ROM), and allowed the BBC to control how long the programmes remain watchable. Programmes were available for download for seven days following broadcast. Once a programme is downloaded, a user had thirty days to start watching it; after starting to watch, a programme remained available for the next seven days. Using the online streaming service, most programmes became unavailable from the website after seven days. Criticism was levelled at the iPlayer's use of KService from Kontiki, the peer-to-peer application which continued to use users' bandwidth even after the iPlayer had been shut down. However, the Kontiki P2P system was not used after the new client was introduced in December 2008. The client offered an electronic programme guide (EPG) with listings for both the previous seven and next seven days' programmes; selecting a programme which had already been broadcast began downloading it immediately, while those not yet shown would be downloaded when available. It was not possible to schedule a series to be automatically downloaded when the next episode becomes available. Online streaming service The BBC's streaming version of the iPlayer, using Adobe Flash software, was launched on 13 December 2007. The BBC made use of the Christmas period to trumpet the new service with
