Subjectivity Will Kill Your Media Buying
Everyone is media expert...they have their own favourite TV show, their pet radio announcer or their loyalty to a magazine, newspaper or website.
When overlayed into the commercial scene the "expert" knowledge can work against the outcomes as subjectivity creeps into the equation.
Being subjective, rather than objective may result in your hard earned media dollars being wasted just for the privilege of hearing or seeing your message in your own familiar media environment.
