The Knowledge-Gap Hypothesis ● It was first proposed by Phillip J.Tichenor and his colleagues The concept of a digital divide is linked to this hypothesis, although its development was independent. ● In the article,"Mass media flow and differential growth in knowledge"that Tichenor and his colleagues proposed in 1970,it is clear to describe "knowledge gap hypothesis": As the infusion of mass media information into a social system increases,segments of the population with higher socioeconomic status tend to acquire this information at a faster rate than the lower status segments,so that the gap in knowledge between these segments tends to increase rather than decrease.The Knowledge-Gap Hypothesis  It was first proposed by Phillip J.
