The document discusses the effectiveness of combining a magazine product with billboard and radio advertisements. It analyzes how the author linked different elements across the products, such as duplicating the magazine logo on the billboard and incorporating a quote from the magazine article into the radio script. The author believes they were mostly effective by maintaining consistency of elements like fonts and images, while also developing elements for different formats. However, the author notes they could have improved the combination by using a single color scheme throughout all products to better link them visually.
