Hong Kong’s Mass Transit Railway (MTR) system remains one of the most impactful advertising channels, even in today’s increasingly digital landscape. Although traditional in format, MTR advertising offers an immense reach. With a population of approximately 7.3 million, and an estimated 5 million people using the MTR daily, the scale of exposure is undeniable. In particular, placing large-format brand advertisements in high-traffic stations like Causeway Bay—a hub for both commerce and business—can significantly boost brand recognition.
