This is said to be the first time Five Star has officially appointed an agency-of-record, as the creative business was previously handled in-house or outsourced on a project basis.
The creative pitch was called in July, with a shortlist of four drawn up.
Established in 1998, Five Star was acquired in 2006 by Best Buy, a US-based consumer electronics retailer. Five Star claims to be the third largest retail chain among the electronic retail industry in China.
