Hello London, the media partnership between Transport for London (TfL) and Exterion Media, has launched DX3, London’s newest digital advertising channel with the support of telent’s technical expertise.

From February 2018, 60 digital displays will be installed across London’s underground network, exhibiting dynamic, full-motion content, which can be watched by customers when standing on station platforms.

The displays are 4.5m x 2.4m in size and will be located at 15 different tube stations within Zones 1 and 2, starting at some of the most popular stations including Liverpool Street, Piccadilly Circus, Holborn and Oxford Circus. DX3 enables advertisers to reach one of the world’s most diverse audiences, with millions of people using the London Underground each and every day.

The DX3 project acts as part of Hello London’s wider strategy, which looks at creative ways to increase revenue and enhance advertising, with significant investments from TfL.

Adrian Lovejoy, Exterion Media Service Delivery Director, explains: “Developing and launching London’s newest full-motion digital network across the London Underground has been a complex engineering challenge. Every station environment is unique and we’ve worked to exacting standards in partnership with NEC Display Solutions who have developed the technical projector design. Lovejoy continues: “Together with telent Technology Services, who have provided installation expertise, we have collectively delivered an industry leading visual experience.”

Steve Dalton, Managing Director, Transport, telent, comments: “telent are delighted to have been involved in such a dynamic project, redefining the experience of the London Underground for everyone who travels on it. We have an excellent working relationship with TfL, NEC and Exterion Media and the project was a great effort from all involved.”
