History
Origin and slow pace of implementation (2011)
On 25 October 2011, the Government of India approved the National Optical Fibre Network (NOFN) initiative, later renamed as BharatNet,[ to connect all 250,000 gram panchayats in the country covering nearly 625,000 villages, by utilizing the existing optical fibre network and extending it to the gram panchayats.] To achieve this, Bharat Broadband Network was incorporated as a Special Purpose Vehicle(SPV) on 25 February 2012 under Companies Act of 1956. Between 2011 and 2014, project did not take off as planned,[ and only 350 km of optical fibre, out of 300,000 km optical fibre network needed for the Phase-I, was laid.][ Between 2014 and 2017, the original Phase-I target of laying 300,000 km of optical fibre was completed under the new BJP government.][
