Video advertising is a type of digital advertising that uses video content to promote products, services, or brands to a target audience. Video advertising can take many different forms, such as pre-roll, mid-roll, or post-roll ads that are played before, during, or after a video content, or sponsored or branded videos that are produced by or for an advertiser. Video advertising can be delivered through different channels, such as websites, apps, social media, or TV, and it can be served and managed through different technologies, such as VAST, VPAID, or MRAID. Video advertising can be effective at engaging and entertaining users, at delivering a compelling and emotional message, or at driving action and conversion. Video advertising can also be expensive, complex, or intrusive, and it can be subject to different regulations, standards, or practices regarding privacy, consent, or quality.
