Professor David Crystal’s world-leading research on language policy, diversity and usage,
conducted at Bangor since 2000, has led to a transformation in terms of public and political
attitudes, both nationally and internationally, towards the nature and use of language in public and
private discourse. In particular, the research has led, since 2008, to an increased awareness of
linguistic diversity, changes to governmental policies on language, and the development of the
world’s first targeted online advertising technology, which today indexes billions of impressions
across 11 languages to provide real-time data services in the emerging online advertising world.
