According to the annual plan of BBC，the academic journal of the BBC Research & Development department and also the data statistics from reliable media website，it is evident that there are new changes in the genre，production and distribution of British documentaries in this new media age. In terms of genre，interactive and virtual reality documentaries are emerging with the help of technology innovation. Aside from that，looking into the production aspect，crowd-funding is further developing and hence more and more independent documentary filmmakers are surfacing. Last but not least，the distribution of British documentaries through new media platform is widely accepted by the audience and therefore are being used by distribution companies. For instance，BBC has released its streaming platform to attract the younger generations’ attention. It is a judicious move to try to survive in this fiercely competitive industry.
