What was the major disruption to TV technology following stereo audio?

The major disruption to TV technology following stereo audio was the transition to Digital TV (DTV). This shift represented a significant change in how television signals were transmitted and received. Digital TV allowed for more efficient use of the electromagnetic spectrum, enabling clearer picture and sound quality compared to the analog signals that preceded it. It also facilitated the incorporation of new features such as multicasting, which allows multiple channels to be broadcast simultaneously, and enhanced video resolutions, leading to an overall improved viewing experience.

The move to DTV also laid the groundwork for subsequent advancements like High Definition Television (HDTV), which further improved image clarity and detail, but DTV itself was the foundational step that initiated these advancements. Digital technology has enabled greater flexibility and interactivity in television content, setting the stage for the future of broadcasting, including the rise of streaming services.

Thus, while other advancements in TV technology followed, the shift to Digital TV was the most impactful change occurring after the introduction of stereo audio, marking a turning point in the way content was delivered and experienced by viewers.
