That's just this one place called film city which is kind of like a business district where a lot of news orgs are based.
The name stands for north okhla industrial development area, there's lots of big manufacturing plants, electronics, autos, all sorts of other industry there too. It (greater noida) is also quite well planned compared to Delhi proper, big roads, decent infra, lots of very nice housing societies, shopping markets, some golf courses, the formula one track and sports complex.
The expressway to UP is also pretty impressive, they have modern amenities like free phone booths to call for rescue in case of a road emergency (though I heard the villagers have tried to steal those phones thinking they can use then lol), good eating joints and guest houses all along the way. It has cut down travel time bet Delhi - UP a lot and has been a boon generally. Traditional zameendaars/land owners have done really well for themselves, made some absolute killings in certain cases.
Go there are see for yourself.
