The term _interactives_ is used throughout this study to describe news outputs in
the sense set out by Nichani and Rajamanickam (2003): the purpose (or function) of these
digital products is to facilitate explanation through interaction. The term is appended
with _news_ simply to delineate the source of origination__news interactives_ are created
within the news industry, in a context of news production. It is acknowledged, however,
that this is definition is coming under increasing pressure: for example, the _Hacks and
Hackers_ social events, established in Massachusetts in 2009, and the Data Journalism
Handbook (Gray, Chambers, and Bounegru 2012) have problematised what it means to
create interactive news, and what it means to be a journalist in this field.
