I am now even more convinced that AdTech marked a new phase for the acceptance of online publishing in the UK. Maybe it had happened already and I missed it. I have now had a look at the new Haymarket directory site - BlueBoomerang. This is comprehensive in market sectors including print and direct mail. The focus is shifting towards digital, however slowly in some cases. At Digital Print World there will be software that could be used for direct mail in hard copy or email. Printweek covers this to some extent.
Meanwhile here are some photos of slides from Google University. Other numbers are available but the overall picture seems clear enough. This is based on current UK, so the growth of broadband will move it further. A stand for Brand Republic at a future AdTech is a strong probability.
