Instagram's Stories feature, which launched one year ago, has achieved widespread engagement among businesses that want to raise their brand awareness and expand their e-commerce penetration, the company said. The tool, launched in August 2016, allows users to create digital slide shows out of photos and videos in order to convey a story. Businesses ranging from Taco Bell to J.Crew and Starbucks have used Stories to give a behind-the-scenes peek at new products, launch limited sales, or get instant customer feedback about new initiatives.
