Digital design company magneticNorth has created the new online and mobile websites for the BBC Proms.
The new site goes live today and features easier ways to watch performances online and book tickets for the 2011 Proms season, which gets underway in July.
When it begins the audience will be able to listen in HD sound, or catch up on every broadcast prom for at least seven days after the performance. People on the move can listen live on their mobiles.
Steve Grace, commercial director at magneticNorth, said: "When the Proms was started by Robert Newman and Henry Wood in 1895, it was to bring the best music to the masses. This site supports these values today by giving more people access to the experience, and the ability to watch and listen to the incredible variety of prom performances."
This is the second BBC project from magneticNorth in as many months, having already delivered a new Desert Island Discs website for Radio 4 in March.
