Analysis of Correct Answer (Radio)

• Radio: This is a quintessential traditional offline advertising medium. It involves broadcasting audio advertisements over airwaves to a wide audience. It predates the internet and does not require a digital connection for the end-user, making it a classic offline channel.

Analysis of Incorrect Options

The other options are all examples of digital online advertising, which are used to drive both online and offline sales but are not traditional offline channels themselves.

• Social Media: Advertising on platforms like Facebook, Instagram, or WeChat is fundamentally an online activity. While it can be used to promote offline stores, the channel itself is digital.
• Display Remarketing: This is a purely digital strategy that shows online banner ads to users who have previously visited a website. It relies entirely on internet technologies like cookies.
• Email: This is a form of direct digital marketing. It uses the internet to send promotional messages directly to a user's inbox, classifying it as an online channel.
