Stato's delight, and things look bright.

If a few statistics get you going feast then your eyes on the latest mobile marketing research published in the Guardian:

"Ten years ago, using phones to download video clips, listen to music, play games or search the internet seemed a distant prospect. Now, those activities are commonplace. Research carried out by Orange earlier this year revealed the popularity of those practices among all age groups. Over half use their phones to access the internet, 64% send picture messages, 55% play games, 49% listen to music and 26% receive email. Some 87% use mobile media at home, and 73% when they are "out and about". Just under half said they used their phones to access the same sites they use on their PCs and 62% said they wanted their phones to do the same things their PCs can. The worlds of computing and telephony have already merged in the minds of many consumers."

With your audience permanently switched-on, impulsive and ready to interact at the drop of a hat, states James Robinson, who wouldn't want to tap into mobile marketing...and digital interpretation for that matter.

One more snatch of stats before we move on:

"...12 million people in the UK are now looking at the internet on their phones each month, and the number of consumers using handsets to search online increased by 37% in 2008, driven by 3G phones and new products, including the iPhone. Until the first few months of 2008, that figure had stubbornly refused to rise for many years. "

Now if those figures don't make you stand up and say 'I better get a wriggle on and develop some digital content for my site', then nothing probably will. Technology moves at a tremendous pace and as mobile internet becomes the norm visitors will increasingly expect to access information, in a variety of formats, to learn and discover the place they are visiting.

Whereas audio trails had to be downloaded pre- or post-visit just a year ago, today visitors can turn up on site, without any prior knowledge of any existing audio interpretation, open their mobile internet browser and play the tracks as they make their way around the route. Take a look at this working example in Kent. There is of course the caveat of reliable mobile phone reception, but if the experts are correct then this will only improve for the more remote locations we want to interpret.
