Digitalization has profoundly transformed our communicative and linguistic environment, and the language used most in digital media around the globe is English. The articles in this book present new research focusing on the ways in which the English language and its speakers are influenced by digital modes of communication. Traditional notions of language contact and change are being redefined, and data obtained from digital platforms offer new answers to old questions. In addition to descriptions of linguistic development, the book illuminates sociolinguistically motivated perceptions and performativity regarding English language use in diverse digital media environments.
