Just not good enough - why do we love banners?

What a waste! E-Mail is a critical component of e-commerce but it just thought of as a retention tool but flashy banner ads that are placed in God knows where are where we spend. Ouch. Not only are banner ads taking a majority of the budget there is very little knowledge of where they are being run and the audience that is seeing them. Behavior targeting/vertical ad networks might help that but we are a long ways away from marking that happen.
