The Greater Anglia franchise was formed by the merger of the InterCity Great Eastern, Great Eastern and the West Anglia half of the West Anglia Great Northern franchises. It was renamed as East Anglia in 2016.
In 2004, National Express won the right to operate the then new Greater Anglia franchise. It was branded 'One' which was an acronym for "Operated by National Express".

In 2008, the franchise was rebranded 'National Express East Anglia'.
In 2012, the franchise was awarded to Abellio who branded the franchise as Greater Anglia, after the official franchise name.
Abellio Greater Anglia
In late 2013, Greater Anglia's name and logotype were merged with its parent company.
2016 - present
In 2016, the name Abellio was dropped from its logo, similar to the earlier logo in 2012 and 2013, while retaining the font. At present, there remain train carriages whose liveries are yet to reflect this change.
