A range of literature on the very general theme of interactivity in online news
production has some bearing on the present study, but only at a tangent. These can
broadly be classified as either functional studies (Tankard and Ban 1998; Kenney,
Gorelik, and Mwangi 1999; Shultz 1999; Rosenberry 2005), concerned with how
interactive elements in online news are presented; and perceived studies (Chung 2007;
Larsson 2012), concerned with how interactivity is understood by the audience.
