While the full-power television switch-off did not occur for another decade, this date marks the official "invention" of digital television as a broadcast standard for the public airwaves. On this date, the Federal Communications Commission (FCC) officially authorized the ATSC (Advanced Television Systems Committee) standard for broadcast television.
Major Events Leading to the Digital TV Birth
The invention of efficient video compression algorithms in the late 1980s, such as MPEG-2, was the critical breakthrough that finally made digital television broadcasting feasible by drastically reducing the bandwidth needed to transmit high-quality video. The concept of digital video transmission emerged in the 1960s and 1970s, largely confined to military and space exploration applications.
Early digital signals were used for satellite communications, but the sheer amount of data required for a moving image made it impractical for consumer television at the time. These early deployments served as real-world testing grounds for the technology, allowing providers to refine the user experience, from the set-top box interface to the digital program guide, long before the switchover from analog signals began.

Japan also pioneered its own ISDB-T standard. Digital television, as we understand it today, is not the product of a single invention on a specific day but rather the culmination of decades of research, international collaboration, and iterative engineering.
