Some Observations :-
It will be interesting to Review What exactly the TV Broadcast Pattern will be observed by the Merger Entity (Sony+Zee)
When "Ten Sports Network" was handed on 'Sony' immediately Sony Sports Network renamed the Property with Prefix 'Sony'.
After Merger there are 3 Possibilities
1) The Entire TV Network gets a New Name (of their New Company Name which they will get Listed with various Legal Authorities)
2) The Entity will be Rebranded with Prefix "Sony" to all Channels following "Zee" Name. Example:- "Sony Zee TV" or "Sony Zee Cinema" or "Sony Zee Max". But it will look very Odd to Pronounce as well as to emerge before Subscribers.
3) The Entity will Continue as like of Now with Same Channel Name without Disturbing each other just what Star / Disney mutually does. They have not renamed or abolished the "UTV" Brand but sharing the Star India Content on "UTV".
As per Market Speculation No.3 Option will most probably be carried by the Merger Entity.
Rerun GEC / Channels :-
Now the Merge Entity possess 3 Rerun GEC in their Port Folio
1)Zee Anmol
2)Sony Pal
3)Big Magic
The Programing Head of the Channels will now have a Challenge to rearrange the Content and Program Schedule on each and every 3 Channels as all 3 are available in DDFD as well as Pay Platforms.
Repetative Contents on these 3 Channels will now Mark the Exit Gate of that very Channel.
Most probably "Big Magic" will be Shutdown and 'Anmol' with 'Pal' will share the Both Libraries accordingly.
As
@Shantanu Bhai said earlier now "&" Brand will receive More Challenges on Both GEC and Movie Channels.
'&tv' requires a Severe Rebranding with More Variety of Program in terms of Serials / Reality Shows / other Sitcoms.
Or else the Merger Entity can utilise their OTT Contents on "&" Brand.
Both "&pictures" and "&xplor" can merge into one Movie Channel or otherwise "&pictures" can be utilised with Hollywood Dubbed Library of Sony and Zee whereas "&xplor" can be utilised with Specific Select Bollywood Titles (like SGS) of both Sony and Zee.
So more Exciting Library / Content Sharing is Upcoming in and after 10 months.
May be at that time Trai will enforce NTO 3.0 and "Sony-Zee" will Publish New RIO with all Available Channels.
