I think there should be a channel anniversary thread. Its title should be updated as and when there is a new anniversary. For instance:
1 Sept.: Zee Anmol, Zee Anmol Cinema, Zee Sarthak, Zee BR/JH, Sony Pal, Sony Mix, TLC, Pitaara.
Moreover today is the 8th anniversary of TLC as they rebranded from Discovery Travel & Living on 1 September 2010.
