The first television to feature RCA inputs was the RCA Model 630-TS, released in 1946. This model was notable for its innovative design and was among the first to use the now-standard RCA connectors for audio and video, which greatly improved connectivity for external devices. The introduction of RCA inputs marked a significant advancement in television technology, allowing for better integration with various audio and video equipment.
In 1949, RCA created the very first ever 45 rpm Vinyl record. It was 18 centimeters in diameter and also it gave about three minutes of time on each side. It was light, compact, and much more durable then the previous models.

Although the first operating television system was demonstrated by John Logie Baird in 1925, the system used a rotating disc to form an image. It therefore is classified as an electro-mechanical system. Despite the system being somewhat cumbersome, the BBC used it for their first television broadcasts in 1929. It was down to Philo Farnsworth to eliminate the moving parts. He demonstrated his own version of the electro-mechanical system in 1927 but by 1929 he showed off the world's first fully electronic system that had no moving parts. RCA used Farnsworth's system for their first commercial broadcasts but because of legal battles, the commercial launch was delayed until 1939.
1963 Philips introduced the compact audio cassette medium for audio storage in Europe in 1963, and in the United States in 1964, under the trademark name Compact Cassette. Although there were other magnetic tape cartridge systems, the Compact Cassette became dominant as a result of Philips's decision in the face of pressure from Sony to license the format free. It went on to become a popular (and re-recordable) alternative to the 12 inch vinyl LP during the late 1970s. source: wikipedia article for Compact Cassette.
