Солтүстік Ирландияның C9TV телеарнасының тарихы

C9TV (Channel 9 Television) was a local television station based in Derry, Northern Ireland. The station's licences were awarded by the ITC (now Ofcom) in 1996 and allowed the station to broadcast to Derry, Limavady, Coleraine and Strabane, although broadcasts would not begin until the night of October 17, 1999. The channels signal also spilled into County Donegal in the Republic and could be received in the northeast of the county. Along with Belfast's NvTv, C9TV was one of two local or 'restricted' television services in Northern Ireland. C9TV would eventually cease operations after years of suspected financial trouble in 2009.

While most RSL local stations in the UK refer to themselves as "Channel 6" or "Six" or similar, the number 9 reflects the large number of stations receivable in the area. All 5 UK wide services could be received in C9TV's transmission area, although Five coverage via analogue was weak in some parts. The Republic of Ireland's four channels could be received (from the Holywell Hill transmitter outside Letterkenny at high power), although only 3 had launched when C9TV was being conceived (though not by the time it had launched), resulting in the channel getting ninth place. Reports on the network's signal coverage were incredibly mixed, the networks official webpage as early as 2002 claimed that they could be received as far as the Colraine area however this does not match the reports of residents from those areas, who claimed that the network's signal was not receivable in those parts, indicating a power which was just strong enough to cover parts of greater Derry City, Donegal and Strabane. During the final years of the network's existence, signal strength was described as greatly reduced and poor, with some areas of the city not being able to receive the channel in the period before its eventual closure.

From approximately October 1999 until sometime around 2005, the station was directed by Tony Deehan as well as his other family members who directed fields in the station such as Financial Direction (which was operated by Terry Deehan), Advertisement Scheduling (which was operated by Garvin Deehan) and Advertisement Productions (which were operated by Darren Deehan.) At some stage around 2005, the network was taken over by businessman Alan Cummings who would direct the station during until its subsequent closure 4 years later in 2009. The network was initially based in the Spring Growth House area of Derry during the first few years of its operations from approximately 1999–2001, although this location was still listed on the stations webpage as late as 2003, despite having relocated to the well known Spencer Road location at some point in late 2001.

Soon after the network had ceased operations in 2009, the networks then owner Alan Cummings had plans to relaunch the station and relocate it from its former Spencer Road location to a much smaller studio at the University Of Ulster (Magee Campus), where it was planned that students would be involved in a heavy amount of the programme creation and production. Changes were allegedly made to the stations former website after he had bought the station with claims of a relaunch and "Coming Soon" being present for an unspecified period. After a long period of silence, it was announced at some point around 2012 that the plans of a relaunch had been cancelled and that the station would no longer return to Derry. The stations website, which was last majorly updated in Spring 2004, was left dormant and inactive for a few years until it was finally purchased by an unknown individual from New York, who used the station's old webpage to advertise "Verizon" mobile related services. The website was finally taken offline sometime around 2018, but was relaunched in 2020 and currently serves as a historical and media archive of the network's existence.
