Vacuum tubes were first used in the 1910s in very small quantities because they were so expensive. Originally, they used directly heated cathodes, but once the switch was made to indirect heat, they became more widely used in radios. These tubes would aid in the invention of transmitters, receivers, and speakers. When it came to the invention of television, electron beams from these tubes would strike a phosphorescent surface within a cathode ray tube to create the picture we see. The concept of how the vacuum tube works seems quite complicated and I find myself unable to fully understand what I am reading on it. Without it, video and sound development for radios, television, and computers would not have been possible, but the finer details of how it works seem too complicated for someone like myself with no experience in electronics to understand.
DISCO: One group I would add to this category is KC and the Sunshine Band. They were a large part of disco. They did not use technology in their songs, and it does not appear they do in their performances, other than a little editing of their videos. KC AND THE SUNSHINE BAND BOOGIE SHOES PUNK: One group I would add to this list is Green Day. They have been making music since 1986 and utilize technology with the usage of recording electric instruments, but not much else with the music itself. They use technology during their concerts tossed live edited video onto the screens behind them. GREEN DAY JESUS OF SUBRUBIA LIVE NINETIES: Oasis is the group I would add to this category with their very well known song "Wonderwall". The song was released in 1995 and did not use much technology for the song. They are seen as one of the biggest bands of the 90s and have influenced lots of British music and culture to follow. They utilized technology in videos like that for Wonde
