Fun Radio's principal shareholders have been GCap Media and Hit Entertainment, but since setting up the station in 2005, both companies' corporate structures have significantly changed.
Both parties will still support the station with GCap's content division, Creation, continuing to manage the day-to-day operation for the stations' programming, while Hit Entertainment will continue to use Fun Radio to promote its brands and activities.
Fun Radio's commercial policy will be driven by the Folder Media team, but will continue to be sold by Global Radio Sales.
Media Week understands Folder Media is looking to adopt the Heat Radio commercial model of a limited number of advertisers being long-term partners of the station.
Folder Media will also focus on exploiting the station on multiple platforms and online. It is looking at developing the station's presence on social networks such as Facebook and Twitter, as well as its online and email marketing activity.
Matt Deegan, Folder Media's creative director, said: "Fun Radio is a successful little radio station that is well loved by a growing audience. Its audience size, when ranked alongside children's' magazines, shows it to be a great choice for advertisers wanting to reach young parents and their children. We're very excited about it joining the Folder family."
Folder Media's managing director Gregory Watson added: "Fun Radio has the opportunity to be a truly multi-platform radio station with multiple touchpoints for listeners and advertisers. It is underpinned with a strong audience on DAB radio in London and will continue to be served by the growth in DAB penetration. While the internet and digital television are great for reach, it is hours that provide the inventory for our partners and it is our DAB listeners that deliver those."
Fun Radio will continue to target the under-10s.
