This document summarizes the knowledge gap theory and digital divide. The knowledge gap theory proposes that as mass media increases the distribution of information in a society, those with higher socioeconomic status will be able to acquire and understand the information at a faster rate than those with lower status, widening the gap in knowledge between the two groups. The digital divide refers to the gap between those who do and do not have access to digital/internet technologies. Those without access are unable to receive information disseminated online and risk falling further behind in understanding and interpreting new information. Bridges must be built to close these gaps and achieve universal access to information.
