Why is "Multi-channel transition" trending?

Wikipedia Overview

The multi-channel transition was a period in the history of television that spanned from the early 1980s to the late 1990s. During this period, multichannel television became popular in much of the world. Many changes happened during this transition, such as the invention of the remote control, the video cassette player, and analog cable systems expanding viewers' choice and control. This era gave viewers more choice and control over what and when they wanted to view a program. Viewers were able to defy the networks' schedules, because they could record the program and watch it whenever they wanted, using the VCR and later the DVR. Producers adjusted to the government regulations and networks lost some of the control they had over program creation. Subscription channels emerged with no advertisements and the method for measuring audiences became more precise with the people meter, with broadcasters fundamentally changing their approaches to programming to accommodate the new device. In the United States, the transition effectively marked the end of the network era, a period in which the three major networks dominated the industry. Once the transition was complete, the post-network era followed, which included a canon of critically acclaimed series known as the Second Golden Age of Television.
