Olympic plans already taking shape
This is a blog that should last a bit more than three years.
The BBC's London Olympics project is underway, and we know the Games of the 30th Olympiad will take place in the summer of 2012 from 27 July to 12 August.
Between now and then you can keep tabs on what we're up to, and I'll answer as many questions and comments as I can.
2009 is a year when there'll be a relatively small amount to see or hear on air about the Olympics, but the decisions we're taking now will have a big impact on what will dominate our screens and radios in 2012.
One example: we need to decide soon where our main studio is going to be, and how it's going to fit in to our pattern of live broadcasting.
In Beijing the Chinese authorities built a special broadcasting tower in the form of the Ling Long Pagoda just ahead of the Games, but we sense a Pagoda in Stratford is somewhat less likely.
So we're working with our partners to identify the best locations - and similarly some of my colleagues made their first visit to Weymouth this week to look at the sailing venue and think about where we'll establish our base.
As well as the logistics of the sport operation, we're starting the planning for BBC News across the UK and for our global and regional services too.
The Olympics are quite simply the biggest event in the world, and we want to tell the story of the building of the Games as well as being the place where you can follow every moment in 2012.
That will involve not just TV and radio but online, on-demand, mobile, information streams and all the rest: the most intensive use of digital services in our history.
This long-term planning applies to the Cultural Olympiad too.
It's fair to say that the Cultural programme of the Games hasn't made much impact yet, even though it's already under way.
But the aim is that the United Kingdom has brilliant performances and events that will live up to the original idea of the OIympics as a festival of the arts as well as of sport.
Orchestras are booked years ahead, so the 2012 Proms season - which will have an Olympic flavour - is already taking shape. Meanwhile, we've started the search for ideas in entertainment, comedy and drama too.
Before anyone says it, it's important we don't bore audiences senseless by doing too much too early.
So a fair few dreams already... and a variety of programmes being considered for 2010, 2011 and 2012.
And it would be barmy to do too little.
Three-quarters of the population watched the Beijing Games, and that figure will be even higher for London when there's no time difference - and when we talk about "bringing the nation together" this is a once-in-a-lifetime opportunity to do just that.
Even for the minority of sport-haters, as taxpayers they're paying for the Olympics and will want the BBC to report fairly and impartially on the issues.
We hope, too, that avoiders of the 100m will still manage to enjoy some of the music and arts.
So there's much more detail to come as we get into our stride.
As I write, it's just 1114 days to go to the opening ceremony. There'll be many twists and turns along the way, but it should be an epic journey.
