What is the term for a form of advertising that uses the internet to deliver business marketing messages?

The term that best describes a form of advertising utilizing the internet to deliver business marketing messages is indeed online advertising. This encompasses various methods and platforms specifically designed to reach an audience through digital means. Online advertising can include display ads, search engine marketing, banner ads, video ads, and social media promotions, all aiming to engage users where they spend time online.

While social media marketing is a component of online advertising focusing specifically on platforms like Facebook, Twitter, and Instagram, online advertising itself encompasses a broader array of internet-based marketing techniques. Print advertising and television advertising, on the other hand, refer to traditional media formats that do not rely on digital channels. Therefore, the correct choice highlights the overarching concept of internet-based advertising, which is essential in today's digital landscape.
