About Noida:

NOIDA is a department of the government of Uttar Pradesh in Gautam Buddha Nagar District, India. The acronym is also the name of the area (New Okhla Industrial Development Area), that is under the management of the department. NOIDA came into existence on 19th April, 1976 and celebrates 19th April as "NOIDA Day". Sanjay Gandhi set up NOIDA as part of an urbanisation thrust during the controversial Emergency period (1975-1977). The city, which was created under the UP Industrial Area Development Act, has first-class amenities and is considered to be one of the more modern suburbs of Delhi. It is also home to the NOIDA Film City.

The land within the NOIDA city limits was initially under the Bulandshahar District (approx. distance 37 km), but was later transferred to the Ghaziabad district (approx. distance 16 km). Later still, NOIDA was made into a separate administrative zone as a separate district by Chief Minister, Mayawati. This decision of the Mayawati government came under review from the next government of Mulayam Singh Yadav, who reversed it in 2003, and remerged NOIDA with Ghaziabad. After a period of some 9 months, the decision was reversed yet again in 2004 and the city was once again made into a separate district.
There were some allegations of political favours through low-priced land deals due to these decisions. Presently, the city is a separate district, called Gautam Budh Nagar, with its administrative HQ at Dadri, a nearby town. However, the highest government official, the District Magistrate (DM) stays in Noida. The city falls under the NOIDA-Dadri legislative assembly seat (Vidhan Sabha) and Khurja Parliamentary seat (Lok Sabha).
