The study of internet histories is valuable,which cannot be ignored.But inadequate academic attention leads to its slow progress.Social memory is one of the paths to study internet histories.This article explores node memories of traditional and new media on China’s internet at its 10 th,20 th,and 30 th year.It finds that media memory issued two birth certificates to the Chinese internet(in 1994 and 1987 respectively),which constructed the beginning memory of mutual negotiation.Media memories recalled the diverse Chinese internet in time in a metaphorical way,which reflected the complexity and richness of the Chinese internet and the evolution of public perception.Media memories strengthened some clues of China’s internet histories and invented its tradition.It also obscured the political and social history of the Chinese internet.To develop China’s internet histories,we need not only to learn from foreign theories and methods,but also to absorb the essence of our traditional historical research,in addition to focusing on preserving internet archives and conducting comparative research.
