With the rise of "American"concept of comparative literature in the 1950s and 1960s in Europe and the US, more and more scholars have attended to the comparison, interaction and migration of literature and other arts; as a result, the interart criticism has become a new approach to the study of humanities and expanded to be interart poetics. Since the late 20th century, the rapid development of digital technologies has become a part of our daily life, the interart studies have broadened into the intermedial studies which booms as one of the most active areas of humanities, going with the intercultural and diversified tendencies. The paper makes a survey of the scholarship of international interart/intermedial studies and elaborates on the four focuses: word and image studies, word and music studies, adaptation studies and media transformation studies, thus shedding light on the academic trends of the intermedial studies in the new century.
