Heart Hertfordshire (previously known as Hertfordshire's Mercury 96.6) is a local radio station owned by Communicorp UK and operated by Global as part of the Heart network. It broadcasts across Hertfordshire from studios in Watford. In 2005, it was sold by GCap Media to the Adventure Radio Company although it still carries programming from GCap's successors Global as well as having its website maintained by Global. The station was rebranded on Monday 26 July 2010, but as it is not owned outright by Global, it operates as a franchise.
