About Mediatel

Mediatel is the UK’s leading provider of media tech, data and thought-leadership. With decades of experience in every aspect of media we are connected to the key players and deliver unparalleled reach and influence across the industry and beyond.

Adwanted Connected combines independent media research, analysis and planning apps to provide information in one simple to use platform. It is the UK’s largest single-source of media data and the first stop for agencies, media owners, brands and academic institutions.

We have two products in the UK radio industry, which continues to enjoy very robust advertising revenues. Mediatel built the first automated trading system for UK media, J-ET, on behalf of the IPA and the Radio Centre in 1998 - long before programmatic and big data were industry buzzwords. Over the years J-ET has expanded to include order approval, finance system links, integrated instant messaging and copy instruction management. J-ET also integrates with a number of planning, sales, traffic and finance systems providing complete transparency of trading, with full audit trails. There are currently over 1000 users and over 12 million spots are handled by J-ET annually.

In 2016 Mediatel and Peach created a joint venture business, Audiotrack, to manage copy delivery across the radio industry. Working on behalf of many of the UK’s creative agencies and radio production companies, Audiotrack was immediately recognised by its clients as providing new and greater efficiencies to the market.

In the Out of Home industry Mediatel has two products – SPACE is an industry standard database of UK OOH sites run on behalf of the IPAO and Outsmart; and the Route API enables companies to build Route data easily and quickly into their own systems. API subscribers are able to focus on the added value activities of creating their own planning interface and incorporating bespoke optimisation strategies. Clients of both include OOH media owners, specialists and suppliers.

Adwanted Events runs over 20 conferences, seminars and bespoke events across a range of media and advertising themes and across the globe. The business is particularly strong in TV and ad-tech, running two global events in London, each of which attract around 600 delegates from across the world. Adwanted Events also runs the Media Leaders Awards and the Videonet Connected TV Awards.

Mediatel's highly regarded The Media Leader and Videonet each amplify the events and the event partners by providing authoritative and thought-provoking news and opinion to readers across the 20,000-strong Mediatel Network and beyond. Both provide further promotional opportunities too, from advertising to reports and white papers.
