As a new smart media channel developed by SIE, the screen-based marketing communication campaign, covering multiple outdoor large-scale LED screens of Chengdu, Chongqing, and Leshan, has promoted cross-regional communication coordination by showing identical publicity content on different screens. The campaign is conducted to raise the publicity of the first Sichuan-Chongqing Housing and Urban&Rural Development Expo (Housing Expo) and increase the influence of the Expo in the two regions. To advance the construction of the Chengdu-Chongqing economic circle, the screen-based marketing communication campaign of SIE was presented in landmark buildings of Chongqing.
