Of the 38 broadcasting companies to whom the notices have been sent, 32 had made changes in their share holding pattern without prior intimation to the ministry while 6 had not informed of the changes made on the board of directors.
Officials said that for over an year, the ministry has been engaged in a comprehensive exercise of verifying the ownership and directorship details of all the broadcasting companies that held licenses for running channels.
"The number of channels in the broadcasting space had at one time touched 877 but since several companies could not withstand the scrutiny of the ministry, 61 licenses were cancelled. The number of channels presently functioning is 806 of which 408 are non news and 398 fall in the news and current affairs category," a senior official said.
Many of the channels whose permission has been cancelled were regional channels or new entrants who did not carve much space in the broadcasting sector.
Officials said that after the ministry decided to examine the ownership and directorship details of the companies active in the broadcasting sector, the first step it took was to write to all the 368 companies which owned all the 877 channels.
