The 2G spectrum scam involved the illegal allocation of 2G spectrum licenses by the Indian government between 2008-2009. The licenses, which allow the use of radio frequencies to operate mobile services, were allocated to several domestic telecom companies at 2001 prices by the then Communications Minister A. Raja, bypassing proper bidding. This resulted in an estimated loss of 1.76 trillion rupees to the Indian government. Several domestic telecom companies and politicians were accused of benefiting from the scam. In 2012, the Supreme Court canceled 122 telecom licenses granted during this period and ordered an investigation into the multi-billion dollar scandal.
