Despite all the hype to date AI's usage in advertising has been confined to very niche areas, from re-organising data more efficiently to tagging and organising inventory. AI's massive potential has only slowly built momentum, however, we have finally reached a tipping point where AI is starting to come in to its own. The trigger occurred as Reach lost its pole position as the ultimate metric, being sidestepped by a need for higher and more accurate engagement. Little wonder really, an overwhelming 2.5 quintillion bytes of data is collected every day turning it from marketers' gold dust to their nemesis. It can no longer be properly scrutinised for meaning and in some instances it can even be misleading.
