Fitch joined the WPP stable eighteen months ago and announced the new brand identity in a global webcast to its worldwide associates on 27 April.
The announcement included a film produced and directed by PCI Fitch.
The restructure includes a new website, more simplified name structure and new corporate identity across its eighteen studios.
PCI Fitch head of business development Richard McHardy said: "This is an opportunity for Fitch to present its design vision with energy and purpose. We're providing an integral part of that vision through our live brand communications."
