On Tuesday evening we convened at Google for a spirited debate around loyalty and brand growth. The evening was chaired by James Parsons and featured Jane Lingham and Kirsty Fuller speaking on behalf of 'love' and Laurence Green and Mark Murray on behalf of Byron Sharp's principle that brand growth is driven by penetration. The gender lines were drawn entirely inadvertently and of course the debate and themes were far more nuanced and interesting and reflective of the real complexities of life, business and marketing, than the debate theme would suggest. It was a terrific and educational evening with sudden outbreaks of agreement and passionate disagreement amongst the panel. Great to see so many of you there – the film will be available shortly for those who missed it and need a fast prep in some of the key issues of the moment.
