Zee Keralam is added or going to add before launch in almost all cable/dth but left 2 major players in kerala each from cable(Asianet digital) and Dth(Sun Direct).The both platforms together had a major share that succeeds all others. So Zee should think about adding in these platforms soon.
Zee had published the customer care number of Asianet digital(ACV) and says the subscribers to call them for adding.That means Zee had approached ACV earlier and the deal wasn't worked smoothly. So Zee is expecting a massive complaining towards ACV from subscribers in demand of Zee keralam which will be helping factor for Zee to make a deal with them.
For Sun Direct Zee's fb page etc just replying it will get added soon(Not doing like in the case of ACV). So the deal going slowly.Any of the parties making it slow. Also mostly sun adds non sun network channels (except Viacom sometimes) only after days/weeks/months of launching especially Zee channels are very lately added. Anyway Sun direct surely add this channel but after launch as usual.
