I would say the film world has stopped operating as one. We have divided it into Hindi movies, Bengali movies, Tamil movies and so on. Earlier, there was only one channel and we all knew what was going on. Today, it is hard to keep track of programmes due to the advent of regional channels.
The advent of the Internet exposed the fact that the old business model for newspapers was broken. The world wide web fundamentally changed the media eco-system, challenging established journalistic practice in what is known as the mainstream media: radio, television, newspapers and magazines.
With the advent of genetic engineering the time required for the evolution of new species may literally collapse.
Certainly the advent of technology and electronic commerce has had an immense impact on the real estate industry.
With the advent of chivalry, the art of boxing waned. The evolution of feudal aristocracy, with other and widely different exercises, pastimes and weapons from those of the common people, made boxing unfashionable.
