Mediacom has worked with Mars for many years in many key markets and we have a very strong relationship with them – we work very closely not just with the Mars marketing team but across their business. One of Mars’ key pillars is mutuality which is reflected in the way they work with Mediacom as the agency partner.


We are very proud of the work we have done with Mars in driving growth for their brands and this has been recognised with a host of awards - including Media Week, Campaign, and Cannes.  We believe these awards are a testament to how closely we work with Mars and our integrated approach, both within Mediacom and working in partnership with other agencies.


In December 2014, MediaCom secured the Mars planning business across all segments and in all markets. We followed this by consolidating both planning and buying as of January 2019.


The account win represents a step-change in their approach to media planning & execution which Mediacom is driving the agenda for.
