AlwaysOnMessage and ITN Source have partnered for the release of the Diamond Jubilee Video Tour, a free iOS app which guides users on a GPS-enabled walking tour of 15 of London’s royal locations, with each location triggering a video of relevant archive footage.

Alternatively, if youre not going to be in London for the celebrations – or are just feeling a bit lazy – the videos can be accessed separately in the app.

Once the Diamond Jubilee is over, AlwaysOnMessage says, the app will be developed across a wider range of platforms and multiple languages, and become a full Royal Tour of London app, incorporating greater functionality and more locations.

“I think it’s fantastic that we’ve brought new technology to such a historic and traditional event,” says AlwaysOnMessage  CEO Peter Swain. “We’ve worked hard to deliver an experience that makes the Jubilee more accessible for people who can’t come to London to experience a very special moment in UK history. The iPhone combined with ITN Source content really brings the event to life.”

And with the Jubilee weekend just kicking off, thats it for this week of mobile marketing news. Regular service will be resumed on Wednesday morning – though of course, if anything big breaks before then, well have it for you.
