Here are some key factors and individuals who contributed to this change:
* The influence of folk literature: Folk songs, proverbs, and oral storytelling traditions have always been a rich source of colloquial Telugu. Many writers, including Gurazada Apparao, drew inspiration from these sources to introduce a more conversational style into their work.
* The rise of the nationalist movement: During the fight for independence, the need for a language that was accessible to the common people became more apparent. This led to a greater emphasis on using everyday Telugu rather than the more formal, Sanskrit-influenced language that was prevalent in literature at the time.
* The literary renaissance of the 20th century: Writers like Sri Sri, Vishnuvardhana Reddy, Devulapalli Krishna Sastry, and Rayaprolu Subba Rao spearheaded the use of colloquial language in poetry, drama, and prose, paving the way for a more inclusive and relatable literature.
* The influence of cinema: Telugu cinema, from its inception, has played a significant role in popularizing colloquial Telugu. The use of everyday language in dialogues and songs made it more appealing to a wider audience, further influencing the adoption of colloquial speech.
Therefore, rather than attributing the "founding" to a single person, we can acknowledge the collective effort of these individuals and movements in making colloquial Telugu a dominant force in literature, cinema, and public discourse.
