Untrue. Just to name a few HD channels in added in recent past (Last 4 or 5 years) & some even few days/months after their launch - And Xplor HD, Times Now Navbharat HD, Investigation Discovery HD (Discovery Jeet HD), Aaj Tak HD, Nick HD+, Star Bharat HD, UTV HD, Star Movies Select HD, Sony Pix HD, Times Now World, Living Foodz HD, Nat Geo Wild HD, Sony BBC Earth HD, AXN HD, Colors Cineplex HD, EuroSport HD, Sony Sports HD Channels, And Privé HD, MNX HD, Sony Rox HD, Sony Le Plex HD, .... Also
@Rajkumar @Vadirocks anna will b able to add many Regional HD channels to this list. There were some SVoD HD channels to added which were later dropped bcoz of various reasons
If i go even back then i can list 50 more HD channels which were added by Airtel Digital TV between 2012 to 2017 , some of these r now defunct so airtel cannot be blamed for their removal from the platform
Only Cartoon Network HD+ addition took little longer and Viacom18 HD channels r in pending status bcoz of probably the same reasons which have been shared / discussed by me in the forum
