I've recently started reading 'Stark Raving Ad- a giddy guide to Indian ads you love (or hate)' by Ritu Singh. The foreword is not boring which is definitely a first for me. However, there seems to be unecessary bashing for online advertising. It should come with more proof later or this will seem a little biased to me.

Although I can't necessarily name a successful, innovative online advertising campaign. Probably should look it up.
