The staff of IW Group, an advertising agency, has been in meetings all week about a new product that they have been retained to promote. It has been determined that the target market for the product is children ages 11-13 and their parents. The product has been packaged to reach that audience. They have determined that the company would like to capture 25 percent of the market for their product within four months of its launch and that the best time to launch it is September to hit the Christmas sales market. They anticipate increasing the market by 5 percent per month after the initial release. They have developed an advertising platform and a budget for the six months following launch of the product. They are currently in the process of determining which media to use and how to incrementally increase the advertising in each media outlet in order to reach the largest proportion of the target audience possible for each dollar spent. What stage of advertising promotional planning are they in currently?
