TV commercials, newspaper advertisements, and direct mail are examples of traditional advertising. With a wide reach across TV, radio, newspapers, and mail, businesses in many industries utilize traditional advertising. Some businesses may lack the resources to produce TV ads or conduct mail campaigns and choose to partner with these agencies. Other businesses choose to use traditional advertising agencies because of the creative and effective advertisements they can create. These services often utilize focus groups and surveys to test the effectiveness of their strategies prior to implementation. Businesses engaged in traditional advertising frequently supplement their efforts with other forms of advertising to reach consumers online, such as [email marketing](https://www.g2.com/categories/email-marketing-services)or [social media marketing](https://www.g2.com/categories/social-media-marketing-smm-services) (SMM), as well as [digital marketing](https://www.g2.com/categories/digital-marketing) or [experiential advertising](https://www.g2.com/categories/experiential-advertising).
