Scholars such as Murray Emeneau and John Gumperz made India prominent in the development of sociolinguistics as a field of study through their simultaneous attention to difference and cohesiveness. Later, scholars stressed the ideological mediation of practice, especially the importance of colonial constructions that continue to be relevant in the postcolonial period. Work on specific notions such as mother tongue and medium of instruction, and the salience of English, led scholars to provide insights into multilingual practices in Bangladesh, Nepal, Pakistan, and Sri Lanka. Finally, a vast scholarship on an array of older and newer media forms ranging from early print publications to social media has posed questions about the possibilities of representation and participation. Ethnographic approaches to digital media that focus on the complex dynamics between ideologies and practices have put South Asia at the forefront of studies of communication.
