From 7 May, Discovery Home and Leisure will become Discovery Real Time, targeting a predominately male audience, while Discovery Health becomes Discovery Home & Health, targeting female viewers. Along with Discovery Travel & Living, the three channels will make up the newly created Discovery Lifestyle Network.
Jon Wildman, the Discovery Networks Europe vice-president of UK revenue, said the move would offer advertisers deeper relationships with a more targeted demographic.
The UK is the lead territory in an international roll-out that will see the channels be rebranded across Europe, Asia and Africa.
Robin Paxton, the managing director of Discovery Networks Europe, added: "We are committed to defining and investing in the lifestyle category, just as we reinvigorated the documentary genre 20 years ago. These three brands will enable us to engage at new levels with our viewers, affiliates and advertisers."
