===2009 retune===
The Freeview service underwent a major upgrade on 30 September 2009, which required 18 million households to retune their Freeview receiving equipment.<ref>{{cite news|url= http://news.bbc.co.uk/1/hi/technology/8280067.stm|title= 18m Freeview homes in TV retune|work= BBC News|date= 30 September 2009|access-date= 30 September 2009}}</ref> The changes, meant to ensure proper reception of [[Channel 5 (UK)|Channel 5]], led to several thousand complaints from people who lost channels (notably [[ITV3]] and [[ITV4]]) as a result of retuning their equipment. The Freeview website crashed and the call centre was inundated as a result of the problems. The change involved an update to the NIT (Network Information Table), which some receivers could not accommodate. Many thousands of people could not receive some channels. This included 460,000 fed from relay stations who lost access to [[ITV3]] and [[ITV4]]. Updates were broadcast to enable [[firmware]] changes, but in some cases the receiver must be left on and receiving broadcasts to accept the updates; not everyone was aware of this.<ref>{{cite news|url= http://news.bbc.co.uk/1/hi/technology/8283452.stm|title= Complaints over Freeview retune|work= BBC News|date= 30 September 2009|access-date= 30 September 2009}}</ref><ref>{{cite news|url= http://absolutegadget.com/200910012671/news/television/viewers-enraged-over-freeview-retune-debacle.html|title= Viewers enraged over Freeview retune debacle|publisher= Absolute Gadget|date= 1 October 2009|access-date= 1 October 2009}}</ref>
