ZenithOptimedia are one of the largest communications agencies globally and Posterscope are the largest buyers of Out-Of Home both in the UK and globally.

The joint venture allows Meridian to provide the in-house expertise for ZenithOptimedia’s OOH solutions, whilst Posterscope, overseen by the Meridian team, provide the buying power. We feel this integration is fundamental to bringing our clients’ OOH requirements to life and ensuring they gain maximum value from their use of the medium. Recognising the importance of the investment that clients make in advertising and communications, we believe it should be accountable and quantifiable. Meridian specialise in delivering a return on investment for our clients in the OOH sector by finding the most compelling and effective ways of connecting with consumers.
