Social media platforms hold vast amounts of biographical data about our lives. They repackage our past content as ‘memories’ and deliver them back to us. But how does that change the way we remember? Drawing on original qualitative research as well as industry documents and reports, this book critically explores the process behind this new form of memory making. In asking how social media are beginning to change the way we remember, it will be essential reading for scholars and students who are interested in understanding the algorithmically defined spaces of our lives.Social media platforms hold vast amounts of data about our lives.

Critically exploring this new form of memory making, Jacobsen and Beer ask how social media are beginning to change the way we remember and consider important implications for the role of content in the algorithmically defined spaces of our lives.
