In marketing, a spot is a radio, television, or social media ad that promotes a business or service. In radio, spots are usually played every hour, but more expensive spots that are played every fifteen minutes are available. Television spots have the same basic structure as radio spots. Television spots are more expensive than radio spots and require a more thoughtful design. Online video streaming services, such as You Tube, also offer advertising spots. Social media spots are becoming more and more popular among advertisers. A spot is basically advertising time.
