During my childhood days, at our home, we had a Black and White analogue Television, which looked like the one above. It was not an easy task for the family to maintain inbound signal transmission and subsequent view on this Television (TV). Moreover, the TV would need some kind of cooling in between views due to excessive heat which was generated from the gigantic Cathode Ray Tubes!
It took the youngest boy in the morning to crack the puzzle to ensure constant viewership on the TV when it was required. I was nicknamed "Vision Mixer" by my elder brothers because of the technical skills which I exhibited when it came to home audio and visual system. What happened from then up to now was a natural course with Information and Communication Technology. Decades later, I am now playing with monitors, mice, keyboards, servers, data, databases, etc.
