The document discusses codes and conventions used in print and radio advertisements. For print ads, it notes that the image aims to catch the viewer's eye, the logo and font follow channel styles, and the text includes key program details. Radio ads use relevant sound effects and a voiceover often from the show host. Background music relates to the topic and sound clips tease the program's content. The tone is clear and humorous or serious, and all radio ads close with air time and channel.
