Advertising has been on the socio-economic scene in Pakistan since its inception. Its a grave lapse on the part of us advertising professionals, as well as advertisers that so far we have NOT put in place any mechanisms for testing the efficacy of advertising.
I must also say that a few of the major advertisers do have some in-house research facilities, and do conduct some research on advertising. Overall, though, pre- and post-testing of advertising has yet to be recognized as the vital discipline it is.
