I already stated due to wrong pricing and unattractive content strategy there has been decline in ratings of many channels thus negatively impacting ad revenue. They need to take corrective measures on the same.
All channels of Disney-Star , South Channels of Zee, Hindi GEC + Kids channels of Viacom18 still have stood strong though there would have been some ups ad downs.
English Movie Channels r doing well but it seems advertisers r rather preferring not to buy slots on it and rather focus on reaching out to such viewers on OTT / Digital Platforms. Infotainment channels r performing in average manner, lot of interesting content in this genre is available on Digital Platforms hence large part of audience has made a transition tp it
English GEC channels r performing badly again bcoz of OTT + Affordable Internet and poor content strategy of broadcasters
All in all broadcasters need to rework on their pricing and content strategy and still all TV Channels across genres can do well on TV as a medium
