Why SunTv show Colors circle before add starts

[Chezhiyan]

Also, 90s Doordarshan used to show a timer before news bulletin. Sun TV copied this too for their news bulletins at 1:30pm and 7:00pm.

News timing in Sun TV is 07:30 AM and 06:00 PM...Doordarshan being the forerunner, many of the private channels started afterwards most probably following the same like DD..We should say it as adoption by other TV channels...Not as Copy...
