Its role in the Internet censorship in China is to block access to selected foreign websites and to slow down cross-border internet traffic . The effect includes: limiting access to foreign information sources, blocking foreign internet tools (e.g. Google search, Facebook) and mobile apps, and requiring foreign companies to adapt to domestic regulations . Besides censorship, the GFW has also influenced the development of China's internal internet economy by nurturing domestic companies and reducing the effectiveness of products from foreign internet companies . </P> <P> The term Great Firewall of China is a portmanteau of firewall and the Great Wall of China, and is thought to have been coined by Geremie Barmé in 1997 . </P>
