So much talk this year in the online advertising market about "audience" -- audience insight, audience-centric planning and buying, audience targeting, audience optimization, etc.
But what is "audience"?
Of course there are multiple definitions, but in the context of online advertising I define it as a "self-selected group of people sharing similar attributes". It's not content. It's not context. It's about people, their self-identified attributes, and their attention. Can we agree?
