An advertisement is promotional content that uses words, images, and sounds to promote a product, brand, organization, or person. There are different types of ads, such as the American-style ad, which emphasizes the visual aspect, occupying a large portion of the advertising space, and the packshot ad, which features a close-up of the product in isolation. In regions where reading is from left to right, the packshot of a print ad is generally positioned in the bottom right corner to capture the reader’s attention before they turn the page, as illustrated by the Listerine example.
