WDMP was appointed following a three-way pitch against undisclosed agencies. The process was overseen by Tim Hunt, director of marketing communications at Freeview.
The agency's brief will be to provide direct marketing support in designated 'Digital Switch Over' areas as regions across the UK progress with digital switchover.
In addition, WDMP has been tasked with promoting the Freeview+ set-top box, which works in a similar way to Sky+.
The non-subscription Free-view service spans 48 TV channels and 24 radio stations. Last month Ofcom granted Five a licence to broadcast a high-definition service via Freeview from 2010.
Ofcom's 'Digital Progress Report' for the first quarter of 2009 showed that Freeview was the most widely used digital TV service in the UK. It was used in 9.8m households, representing 38.5% of all homes.
The UK's digital switchover, which began last year, will be concluded in 2012. Digital UK is the independent organisation set up by UK broadcasters to oversee the switchover.
