Theatre, which began as an art form of humanizing the mass gradually stood apart as an emblematic form of artistic expression. Theatre in India especially during and after the independence of India became an artistic illustration of the rich traditions and folklores of India whilst exemplifying the tears, agony, happiness and fears of the Indians. The major groups and companies then aided in carrying Indian drama to the next level of maturity whilst illustrating the modish aspects of Indian Natya in the most vibrant way. The conventional elucidation of the age-old epic plays was no more there. The depiction of the British Colonialism in drama also faded away. The post independence theatre form in India became lot more realistic whilst befitting the socio political and economic scenario of Independent India. The major groups and companies then became the representatives of the common people whilst illustrating their daily life, their voices in the form of Indian theatre.

Ranga Shankara:
Few friends from Bangalore dreamt a dream together. The dream was to regenerate and revive Indian theatre and thus to keep Indian theatre alive.

Apart from scaffolding the best plays all across the world Ranga Shankara also holds the dance festival in order to showcase the best talents in the respective field.

Ninasam:
Nestled at the village of Heggodu in Sagar Taluk of the Shivamogga district in Karnataka, Ninasam happens to be one of the major groups and companies dedicated to the development and growth of Indian Natya. It was the year 1945 when Subbanna, one of the acclaimed Kannad dramatist and writer along with his friend laid the seed of Ninasam as the organization to carry Indian theatre to the next level of matureness. That was just the beginning of a new history and within no time Ninasam stood apart as one of the Major theatre companies and groups to not only stage modern theatres but also to encourage the classical film culture.

Indians People Theatre Association (IPTA)
In the year 1945, IPTA was established for the greater objective of building social consciousness and at the same time to support the national integration amidst the artistry of Indian theatre.

The aim was to revive the rich cultural heritage of India and slowly IPTA stood apart as the leading theatre association of India. IPTA is still reckoned as one of the major groups of Indian theatre and is one of the oldest associations of performing art in India.

Bengali theatre after independence became the illustration of India`s socio political setting and one of the major groups was Chetana, which further reshaped the contemporary Bengali theatre to a great extent. The great breakthrough in the history of Bengali theatre occurred with the theatrical production of "Nabanna" at Chetana. It is still believed as the red-letter day in the timeline of Bengali drama.

Theatre Formation Paribartak
Situated at the Howrah District of West Bengal, Theatre Formatioin Paribartak is one of the major groups and companies in Indian theatre that has aided in redefining the modern Indian theatre. Paribartak staged plays like "Waiting For Godot", "Ekdin Rattire"., "Godot Waits For Homeland Security", "Piano", "Endgame" and denounced the change in the typical dramaturgy of Indian theatre.

Bahurupee:
It is with the establishment of "Bahurupee" by Shambhu Mitra in the year 1947, Post Independence theatre form gained a distinguished elocution. Tulsi Lahiri`s "Pathik", "Chera Tar" and "Ulukhagra" are few of the plays, which aided in carrying the modern Indian theatre to the further level of maturity. The staging of Rabindranath Tagore`s "Raktakarabi" in the year 1954 again created another milestone in the history of Indian theatre.

Indian theatre, which first made its presence felt as a typical form of entertainment, thus gradually became a distinctive form of expression.
