channels function. When users click on a programme by another broadcaster they are redirected to the relevant broadcaster's catch up service (either the ITV Hub, All 4 or My5). In April 2014, BBC iPlayer was once again relaunched with a new look and a different user interface. From October 2014 the BBC extended the programme availability for programmes on iPlayer from 7 days to 30 days. The COVID-19 pandemic from 2020 and the subsequent lockdowns has changed this; many programmes are available for more than a year, and entire series - for example, Peaky Blinders, Top Gear, Killing Eve - are available in their entirety going back to the first ever episode. However for legal reasons most news bulletins are available for only 24 hours after the initial broadcast (with the exception of World Business Report, Business Live, Victoria Derbyshire, Daily Politics, Politics Europe, Sunday Politics and Newsnight) . Some archive programming, such as Timewatch, is available for the long term. Specific applications for mobile platforms were launched in February 2011, initially for iOS and Android devices, where the launch would have the biggest impact. Development The original iPlayer service was launched in October 2005, undergoing a five-month trial by five thousand broadband users until 28 February 2006. iPlayer was heavily criticised for delay in its launch, rebranding and cost to BBC licence-fee payers because no finished product had been released after four years of development. A new improved iPlayer service then had another very limited user trial, which began on 15 November 2006. At various times during its development iPlayer was known as the Integrated Media Player (iMP), Interactive Media Player, and MyBBCPlayer. The iPlayer received the approval of the BBC Trust on 30 April 2007 and an open beta for Windows XP and Windows Server 2003 was launched at midnight on 27 July 2007, when it was announced that only a fixed number of people would be able to sign up for the service, with a controlled increase in users over the summer. The BBC had been criticised for saying that the iPlayer would 'launch' on 27 July 2007, when what was on offer was simply an extension of the beta to an open beta, admitting more users in a controlled manner. This was done reportedly to allow British ISPs and the BBC to gauge the effect of the iPlayer traffic on the Internet within the UK. The
