Richard Watson of NowandNext.com and I have collaborated extensively over the years, including on numerous client projects. Richard is very well-known for his Trend Blend annual series of maps (here are the 2007-2010 trend maps). I collaborated with Richard on several of them but not on the more recent ones, partly as he is now based in London.
Our Trend Blend 2007+ map based on the London subway map spawned an entire genre of trend maps based on city train lines.
Here is Richard’s Trend Map for 2012, once again breaking new ground in communicating trends and ideas. Enjoy!
