The company looks to engage its customers during the four-hour live event, one interactive feature planned for the show will give the audience a chance to win prizes by shaking their phones with the mobile Taobao and Tmall apps open during key moments.

In addition, four one-minute time slots will be awarded to those merchants, consumers and charities who submit the best advertisements or promotions to Alibaba. Those winning videos will be aired during the gala.
