In the past five years, marketing has advanced tremendously with technology enabling ever more refined data and behavior analysis. What was once theory or a rule of thumb is now provable fact for your audience in ways that would make Mad Men drool.
But it is good to review how we got here. Marketing, it turns out, goes a long way back to the Egyptians who first branded their cattle in 2700 BC. It is important to review the history of your chosen profession because some of the great “innovations” of today are often re-hashed versions of what someone did 100 years ago. The great thing is that the direct marketing techniques of the 1960s-90s are today’s growth hacking tools with improvements in speed, data collection, and audience targeting.
