The document discusses the effectiveness of combining a main product (a local newspaper) with ancillary tasks (a radio advertisement and billboard). It describes how the radio advertisement was created using Audacity and Movie Maker to be under 30 seconds, the conventional length. It also details how the billboard advertisement would feature for a local newspaper, using sandwich boards on the high street rather than large outdoor displays. Both ancillary tasks refer to and promote content in the newspaper, like film previews and a website link, creating synergy and making the newspaper feel more realistic and coherent.
