Since the turn of the twenty-first century, scholars and educators working in interdisciplinary fields connected to multilingualism, have been developing new conceptual theory and applied pedagogy. These areas include history, culture, linguistics, literary and media phenomena, as well as technological and pedagogical approaches to multilingualism, and the study of multilingual communities in the United States. Immigration, globalization, the mechanization of language diversity, translation tools, social media, and universal streaming platforms have contributed to the rapid progression of multilingualism.
