It was in September 2009 that I first wrote in this blog about our technical ambitions and the possibility of some 3D coverage of London 2012.
Here's what I said at the time: "We could, and I believe should, capture some of the Games in 3D. Nobody would expect the Games of 2012 to be comprehensively in 3D because the technology will be nothing like widespread enough; but it would be a shame not to have any images of London that were part of an experiment with what will be one of the next big waves of change."
That was followed up last summer with a specific piece about 3D - which generated some pretty polarised comments.
And they, along with market analysis and wider audience research, have helped shape our policy on 3D for London 2012.
