From DVD rentals to streaming services，and to original content production，Netflix，founded in 1997，grew in transitions and survived to become an industry disrupter. This report aims to analyze the bumpy journey and successful experience of Netflix. The first part reviews how Netflix started out as a DVD rental business，developed a completely new streaming business from scratch with the help of the Internet，and finally focused on original content investment. The second part introduces the fierce competition in the streaming media market，and the market environment that Netflix faces through introducing several major rivals，such as Disney，Amazon，HBO and Apple. On the basis of context and case analysis，this report summarizes some inspirations in the development and expansion of Netflix：1. Netflix maintains an acute insight into users’ pain points and the trend of technological evolution. 2. Netflix spreads out strategic layout of video content and channel format. 3. Netflix develops original content，creates content intellectual property，and gains long-term traffic and public praise. That is a path to expansion based on innovation. This successful path of counter-attack convergence development can provide not only inspiration for domestic broadcasting organizations，but also a reference for film and television producers to build an all-media and all-industry chain.
