Obviously, an important point to raise is that we're facing a completely different set of markets - old school could mass market, but the internet and mass media are fragmenting into niche markets, and this is what the new marketer has to adapt to.
Still, there are key principles that should work in both - not least that customer care can (I'd say should) always be an important part of your marketing strategy.
