The new stations in Bristol, Bath, Wiltshire, Reading, Oxford, Plymouth, South Hams, North Devon, Exeter, Torbay, Somerset and Gloucester have today joined the nine stations that launched across Anglia in phase one on 5 January.
Local breakfast shows in each of the 12 new regions officially launched Heart at 6am this morning. Toby Anstis presents the first show on the expanded network from 10am.
To celebrate the launch of the phase two stations, Heart is running a two-week promotion across the network - Heart's Holidays - giving listeners the chance to win holidays to destinations such as Bermuda, Thailand, Bali, Cyprus, Sardinia and Malta.
The rollout of the Heart brand is being supported by an ad campaign, including a refreshed "Give it some Heart" TV and cinema commercial. The ad will run across a number of ITV regions including West Country, HTV West, Central South and Meridian Thames Valley, plus London and Anglia, and in Odeon cinemas across the same regions.
