In 1997, the director general of Doordarshan, Rathikant Basu left the public broadcaster and joined its multinational rival, the Star Network. The resignation brought about a call for scrutinising his activities during his tenure as the director general, a parliamentary committee was assigned to examine the finances of Doordarshan, which alleged "irregularities" in its dealings with NDTV. On 20 January 1998, the Central Bureau of Investigation (CBI) filed a number of cases against the former director general, five other officials of the public broadcaster and against Prannoy Roy who was the managing director of NDTV. The cases went on for several years in the form of a protracted dispute, until CBI filed a closure report in 2013 and the charges were quashed by the Delhi High Court, stating that there was no evidence of wrongdoing.
