Well, don't these words - Accountable & Mass media present an irony of sorts to you?
Yes, surely this has been the way things have been happening for last 3-4 decades. Mass marketing has never been accountable. It's never been addressable 'one household at a time' too. Either, it was not possible or it was too expensive to do it. Technology is surely breaking down these myths and introducing possibilities like never before. Take a look at how this happening or expected to unfold in the near future:
"Since May, Google has been selling ads on the 125 national satellite channels distributed by EchoStar Communications’ DISH Network. Cable networks routinely provide distributors with a few minutes each hour for local commercials; Google is responsible for a portion of EchoStar’s local time and creates an online auction market for it.
Google then analyzes the data from set-top boxes to determine exactly which ads were watched or skipped, with a second-by-second breakdown. With Nielsen’s help, Google will begin to take that information and overlay sampling-based ratings, adding a rich demographic layer to the raw numbers that EchoStar provides."
The reports from Google can pinpoint the moment when viewers most commonly changed the channel, potentially helping marketers shape the creative work on their commercials. For instance, if viewers are turning the channel after seven seconds, the agency might revisit the opening of the ad.
“We see a future in which, when you sit down in front of your television set, you will see ads that are more relevant for you,” said Mr. Steib of Google. “When we make advertisements more relevant to viewers, inventory becomes more valuable and the return on investment is much higher for advertisers.”
