It was founded in 2008 as the Premier Intermediate League for members of the previous IFA Intermediate League that met the new stricter membership criteria, though was marketed as the IFA Championship. In 2009, it was extended to two divisions: Championship 1 and Championship 2 with promotion and relegation between the two. In 2013, the Championship and IFA Premiership were replaced by a single Northern Ireland Football League, independent of the Irish Football Association (IFA). The NI Football League is a private company that has 40 member clubs from the Premiership, Championship 1 & 2, who are each shareholders. The Championship is sponsored by the Belfast Telegraph and is marketed as the Belfast Telegraph Championship.
Results from Championship 1 are featured on the Press Association vidiprinter service. However, they are rarely seen by television viewers as the Saturday results often do not appear until after 5.15pm and therefore are not featured during the reading of the classified results. The results from Championship 2 are not carried on the Press Association vidiprinter service.
Under reforms agreed by the NIFL clubs in 2014, from 2016, the current Championship 1 will acquire senior status, continuing as the NIFL Championship, while Championship 2 will continue as the Premier Intermediate League, retaining its intermediate status.
