Senior media and communications executives met in London this week for the 2010 FT Digital Media and Broadcast conference (#ftmedia10). At the heart of the debate were the questions of how the sectors were emerging from the global recession and the impact of online and social media on the creative industry and its revenues. WPP Group Chief Executive Sir Martin Sorrell launched the opening salvo by questioning companies that, from an advertising perspective, were being over-optimistic about social media. Sir Martin described social media as a phenomenon that was “personal” and therefore “not suited to being invaded by adverts.” He was right. This phenomenon is personal and it works because it’s based on conversational marketing that’s more suited to public relations than advertising.
