China is now at a critical stage for building an innovation-oriented nation. Therefore，facilitating the public to understand，support，and participate in sci-tech innovation，and helping them learn more scientific knowledge is the central task for science popularization. With the assistance from the Chinese embassy，we have carried out a survey on science popularization in a number of developed countries. Based on the research findings，this paper introduces the current science popularization activities in developed countries，summarizes the development trend，and puts forward suggestions for popular science development in China.
