Actually Star India went to dish d2h and sun direct with this promotional offer but they heard sounds of "Dishkiyaaon Dishkiyaaon" coming from office & they went back scared.
After this came turn of Sun Direct and there people were dancing on the Salman Khan song "Tan Tana Tan" , this saddened Star India team as they thought Sun people r poking fun at them for losing rights of new Salman movies.
They remembered that airtel was right "Sab kuchh try karo phir sahi chuno" and along with sister concern Tata Sky they all webt to goa, danced on "Sooral doobaa hai" having their favorite "dish" post which all were so happy & Star gave all sports channels for free.
Please don't ask me about source for this, this is extremely confidential information from "independent" source but i am sharing with u all bcoz i believe in principle of "Jio" toh khul ke jiyo
Don't expect generosity like airtel from Tata Sky. Airtel will keep providing good or free offers on a regular basis by making adjustments here and there while Tata Sky has prime focus of maximising profit. HD is a revenue generator & Tata Sky has almost monopoly over elite base of users, giving HD free will cause loss for them which they cannot agree upon.
U remember airtel giving ling free preview of almost all newly added channels bcoz broadcaster gave it at no cost for limited period or it was included in old deal but Tata Sky never gave such offers. List is endless if i compare what benefits airtel gave vs. Tata Sky withheld.
