Through this blackout, broadcasters aimed to show an advertisement in the form of a warning to those who are still using the service from local cable operators, while trying to convince them to switch over to digital services.
Despite digitization plans and emergence of new DTH services from various operators like Airtel, DishTV, Videocon, TATA Sky, etc there are still many people in some not under-developed areas in these cities who prefer to have cable connection as they find these DTH services a tad expensive.
To phase out the analogue transmission system information, broadcasting ministry has earlier set June 30 as the deadline, but due to lack of set top boxes and several other reasons of technical faults , this deadline has now been shifted to November 1.
Since the trend of multiple channels started in 1992 when only one channel from Doordarshan was available, i.e DD1, the growth of TV viewership has grown manifold and cable industry has grown from 0.4 million in 1992 to 94 million in 2011. Although the speed of digitization is slow but almost 50% of viewers have switched to digital set top boxes in four metro cities in which Mumbai leads with almost 50,000 set top boxes installed every week.
