"In this book, David Crystal, one of the world's authorities on language, brings together for the first time the three major trends which he argues have fundamentally altered the world's linguistic ecology: the emergence of English as the world's first truly global language; the crisis facing huge numbers of languages which are currently endangered or dying; and, finally, the radical effect on language of the arrival of Internet technology." The Language Revolution will be essential reading for anyone interested in language and communication in the twenty-first century.
