How Video Calling Started
Video calling is a technology when you call somebody. You see him at the same time. It is a normal thing for us today. People do not know it one hundred years ago.
People first get the idea of video calling in the late 1890s . They do not know how to do it.
The first success is in the 1930s. But the video is very bad. A US company makes a Television-Phone in 1955. People see each other when they call. The screen is 25 centimeters wide.
The Internet changes video calling in the late 1990s. It is fast and the picture is good.
Many people use video calling every day. They work from home or they must stay at home. They are happy that they can see their family and friends on the screen.
In the late 1890s, people started to think that it could be possible to see the person who they were calling. It was not easy to develop such technology.
In the 1930s, special boots were in post offices, but the video was very bad. In 1955, the US company Kay Lab invented Television-Phone, and they called it ‘the telephone of tomorrow’. The screen was 25 centimeters wide and two people could see each other while calling.
Scientists developed much better technologies in the 1980s and 1990s, but they were very expensive. In the late 1990s, it became possible to use the Internet for video calling and people started to use the technology normally.
Many people started to use video calling in 2020 because they could not meet each other. Funny moments happened sometimes because people could not use the technology well.
Development of video calling started in the late 19th century; however, the technology became available to the public in the 1930s.
These early demonstrations were installed in post offices and they were shown at various world expositions. Attempts to use normal telephony networks to transmit video failed mostly due to poor picture quality and the lack of video compression techniques.
The 1955 invention of Television-Phone was hailed ´the telephone of tomorrow´ when it was unveiled by San Diego´s Kay Lab. The device gave a 25-centimeter view of the person who somebody was calling, and it lasted until one of the persons hang up. Very expensive systems continued to evolve throughout the 1980s and 1990s; however, only in the late 20th century with high-speed Internet broadband, video calling became a practical technology for regular use.
Video calling has become an important part of life since, especially for people working from home during 2020 and 2021, and there have been many mishaps and funny moments, too, while using the technology.
