إجابة الطالب المختصرة من خلال موقع بوابة الإجابات هي
The earliest concept of television's color was patented in 1904.
The concept of color television is surprisingly old, dating back to the **late 19th and early 20th centuries**. Here's a breakdown:
* **Early Ideas (Late 1800s - Early 1900s):** As soon as mechanical television systems were being developed, inventors began to consider how to transmit color. Ideas involved using colored filters and rotating discs to create color images.
* **Significant Demonstrations (1920s - 1940s):**
* **John Logie Baird** demonstrated a color television system in 1928. This was a mechanical system using a rotating Nipkow disc with colored filters.
* **Early Electronic Systems:** Researchers at Bell Labs and RCA were also working on electronic color television systems in the 1940s. These systems were more advanced and would eventually lead to the modern color television.
* **Commercial Broadcasting (1950s):**
* **CBS:** CBS briefly broadcast a color television system in 1950. However, it was incompatible with existing black-and-white sets and had other technical limitations.
* **RCA's NTSC System:** The **National Television System Committee (NTSC)** in the US developed a color system that was compatible with black-and-white televisions. This system was approved in 1953, leading to the widespread adoption of color TV in the late 1950s and 1960s.
So, while the concept of color television existed for many decades, it didn't become a practical reality until the 1950s.
