A “set” implied not a single object but an integrated configuration of parts designed to receive broadcast signals, decode them, and convert them into audio and visual output.
The phrase “TV set” emerged during the early decades of broadcasting, when the technology of home entertainment was still evolving and the language around it had not yet settled into the simplified forms we use today. In the 1920s and 1930s, experimental television receivers were assembled from multiple distinct components, often including a radio tuner, a display apparatus, a power supply, and a loudspeaker.
This advice was especially prevalent during the era of cathode-ray tube (CRT) televisions.
Many parents have cautioned their children about sitting too close to the TV, expressing concerns that it could harm their eyes. The belief was rooted in the idea that the proximity to the screen might strain the eyes or lead to vision problems.
