RSMB was established in 1987 to offer high quality design and operations in the field of television audience measurement. Since then we've earned a reputation for innovation in audience research methodologies that have helped the UK media research industry meet the challenges of rapid changes in consumer media use.

RSMB has been a contractor to BARB since 1989 and this relationship will continue until at least 2029. In June 2021 BARB awarded us a new contract which will run from 2024; this is our fourth consecutive BARB contract and encompasses methodology, statistical design and quality control for the overall service.

RSMB’s expertise has been recognised by other industry organisations. RAJAR (Radio Joint Audience Research Ltd) appointed RSMB as one of the contractors for the service which started in 2007. RSMB’s appointment reflected RAJAR’s desire to be able to respond to the increasing demands and complexity of the UK radio industry.

In addition, the company has worked with clients to develop a number of data integrations and macro models that are regarded to have broken new ground in cross-media research, such as the IPA TouchPoints media planning tool and Comcast/Sky's UK implementation of the CFlight cross platform measurement and reporting methodology. The CFlight methodology is now being enhanced to include ITV and Channel 4.

RSMB is an independent company jointly owned by Kantar and Havas.
