How is online marketing different from traditional marketing?

"The biggest difference between online and traditional marketing is the medium that is used to communicate the marketing message to the audience. Traditional marketing involves producing physical marketing materials and then delivering them via traditional marketing channels, which include direct mailings, print advertising like magazines and newspapers, radio, and television. It can also include in-person marketing events like tradeshows. Online marketing, on the other hand, utilizes digital channels as tools for marketing communication. These tools include online videos, email, content, social media, search engine optimization, and pay-per-click campaigns."
