The Nile River. The Nile is the longest river in the world, stretching north for approximately 4,000 miles from East Africa to the Mediterranean. Studies have shown that the River (Iteru, meaning, simply, River, as the Egyptians called it) gradually changed its location and size over millions of years.
When did color tv's become common in the average household? The KGB Agent answer: While the first color television was introduced in the US in 1953, it wasn't until the late 1960s and early '70s that color televisions became commonplace. Color sets did not outsell black-and-white sets until 1972. A German patent dating to 1904 contained the first proposal for a color television system, however, it failed, along with a second attempt in 1925.
In late 1953, the FCC adopted the RCA compatible system, commonly referred to as the NTSC system. The first color television sets for this system were sold in 1954. They used a 15 inch screen. Later that year, 19 inch sets were made, and by 1955 all sets were made with a 21 inch picture tube. Several manufacturers made 15 and 19 inch sets, most in very small quantities.
