In order to coordinate with the launch of new TV commercials, TCI-HK had planned an Out-of-Home Advertising Campaign in May 2018. A series of prominent outdoor billboards were rented to promote the brand image of TCI-HK. These billboard advertisements were located at the Kowloon entrance of the Hong Kong Eastern Harbour Crossing. We adopted the same elements of the new TV commercial, such as the beautiful scenery with the image of the protagonists in the commercials. The Eastern Harbour Crossing is one of the tunnels with many traffic flows in Hong Kong. The prominent location of the billboards, and the beautiful design of the advertisement, certainly attracted the attention of passersby when going through the tunnel.
