free-to-air channels. As mentioned above, the inhibiting factor from the viewer's perspective is the cost of the STB. Analog switchover The Ministry of Information and Broadcasting issued a notification on 11 November 2011, setting 31 March 2015 as the deadline for complete shift from analogue to digital systems. In December 2011, Parliament passed The Cable Television Networks (Regulation) Amendment Act to digitize the cable television sector by 2014. Chennai, Delhi, Kolkata, and Mumbai had to switch by 31 October 2012. The second phase of 38 cities, including Bangalore, Chandigarh, Nagpur, Patna, and Pune, was to switch by 31 March 2013. The remaining urban areas were to digitize by 30 November 2014 and the rest of the country by 31 March 2015. †Indicates the date when analogue signals were switched off and not necessarily the date when 100% digitisation was achieved. Phase I From midnight on 31 October 2012, analogue signals were switched off in Delhi and Mumbai. Pirated signals were available in parts of Delhi even after the date. In Kolkata, on 30 October 2012, the state government refused to switch off analogue signals citing low penetration of set-top boxes (STBs) required for receiving digital signals. The I&B Ministry did not push for switching off of analogue signals in Kolkata. After approximately the Centre estimated that 75% of Kolkata households had installed STBs, the ministry issued a directive to stop airing analogue channels in some parts of the city beginning 16 December and completely switch off analogue signals after 27 December. On 17 December 2012, the West Bengal government openly defied the directive and stated that it would not implement it. The state government then announced that it would extend the deadline to 15 January 2013. The I&B ministry had initially threatened to cancel the license of multi system operators (MSOs) in Kolkata if they did not switch off all analogue channels. However, the ministries softened their stand following a letter from MSOs, explaining how it they were sandwiched between divergent orders from the Central and State Governments. In Chennai, the deadline was extended twice to 5 November by the Madras High Court. The extension was in response to a petition filed by the Chennai Metro Cable TV Operators Association (CMCOA), who argued at the beginning of November that only 164,000 homes in Chennai had the proper equipment, and three million households would be left without service.
