Zainulbhai replaces Manoj Mohanka, who "had expressed his unwillingness to continue as the chairman of the Board of Directors," TV18 Broadcast Ltd said in a regulatory filing.
Mohanka will, however, continue as non-executive independent director on the Board of the company.
Besides Zainulbhai and Mohanka, TV Broadcast board now has Rohit Bansal, a nominee director of the promoters, and Raghav Bahl, the erstwhile owner of the media company.
Meanwhile, in a separate filing, TV18 Broadcast said that it has appointed Deepak Gupta as company secretary and compliance officer with effect from July 22, 2015.
