Which of the following is NOT considered a digital marketing channel?

Television advertising is not considered a digital marketing channel because it operates primarily through traditional media rather than online platforms. Digital marketing channels typically include any medium that facilitates the promotion of products or services through the internet or electronic devices. Email, social media, and search engines all fall under this category, as they leverage digital technology to reach audiences, engage with customers, and drive conversions. In contrast, television's conventional broadcasting format does not utilize digital technology in the same way digital channels do, making it an outlier in this context.
