On a recent agency tour, I was asked the same question in Atlanta, Dallas and Los Angeles. How can ad agencies convince DR (direct response) clients to run online video advertising? The answer is simple. Before DR clients can or should be "convinced" of anything, the industry has to solve some key issues in order to make online video advertising profitable for them. Otherwise, what the client ends up facing is a series of small budget and, likely, unsuccessful test campaigns that prove to be nothing more than a waste of everyone's time.
