In 1998, three Cambridge graduates sell their first innocent milkshake at a small music festival. After 15 years of development, innocent has become an international brand, recording sales of £209 million in 2012, and has become the largest smoothie brand in Europe (Innocent, 2013a). In 2013, Coca Cola increased its stake in Innocent from 58% to over 90%, since then Innocent has entered a new area. From a small stall to an international company, Innocent has never stopped developing its marketing strategy and has achieved remarkable improvement. However, in some respects, the potential disadvantages remain innocent. Palmer (2004: 18-23) divided the marketing mix into 7 elements: product, price, place, promotion, people, processes and physical evidence. The purpose of this case study is to analyze its marketing strategy starting from 4 elements: product, price, place and promotion. Next you have to compare and contrast the innocents and their competitor. Finally, we will conclude innocent's marketing strategy and discover some feasibility measures. Based on the three-level analysis of product offerings (Palmer, 2004: 253-254), innocent's product mainly belongs to the main level and the secondary level. The main level product provided by Innocent is drinks and food. The company has constantly provided new products to its customers. Over the past 15 years, they have sold a total of 9 kinds of products in the market: Smoothies, Juices, Extra Juice Smoothies, Baby Smoothies, Baby Juices, Baby Fruity Water, Noodle Jars, Vegetable Jars and Fruit Tubes ( Innocent, 2013b). In all these products, smoothies are the main product of Innocent. However, it is already in the saturation phase of the product life cycle. Many competitors have been selling similar products to capture markets. For example, the Spanish juice brand launched one-liter smoothies to challenge the innocent position in a year and a half
