had collapsed, the rights reverted to the regulator and the ITC invited bids for the space on Multiplexes B, C and D. The Freeview consortium was formed by the BBC, transmitter company National Grid Wireless (known at the time as Crown Castle UK) and BSkyB. This consortium (legal name DTV Services Ltd and trading under the "Freeview" brand) won and launched a new service. Dropping the failed ITV Digital business model, Freeview launched on 30 October 2002 with free television channels only, and made digital radio stations available on television receivers for the first time. The BBC controlled one Multiplex (B) for its own services, and Crown Castle/National Grid the other two (C & D) for commercial services, though the Community Channel also operated on Multiplex B. The BBC's second multiplex has allowed it to televise BBC Parliament where it had previously only been available in sound, allowed BBC Knowledge and its successor, BBC4, to stop renting space from SDN for coverage, and allowed for special video screens in its interactive service BBCi, for use during sporting events such as Wimbledon and carrying loops of news headlines and weather, (services already provided on digital satellite) On 11 October 2005, ITV plc and Channel 4 joined the Freeview consortium and in the same year ITV plc also bought SDN and as such they gained control of Multiplex A. Top Up TV The space ITV Digital had rented on other multiplexes initially became empty again, but some were rented out to allow new channels to launch. In May 2004 Top Up TV was launched to provide subscription content in hitherto unused space on multiplex A, rented from Channel 5 and additional services transmitted by Channel 4 on their own capacity on Multiplex 2. TCM purchased its own slot throughout England, Scotland and Northern Ireland from the multiplex owner, SDN, but rents from Sit-up Ltd in Wales, timesharing with bid tv. Multiplex A is ultimately owned by ITV Plc via its SDN acquisition, but ITV only has involvement with Top Up TV channels via Channel 5. In September of the same year, Top Up TV began operating solely on Multiplex A, as Channel 4 reclaimed the bandwidth on Multiplex 2 for its own services More 4, E4, and most recently Film4. In October 2006, Channel 5 launched two new free-to-air digital channels, Five Life and Five US, using capacity formerly leased out to
