Gaming history part 1

People believe differently depending on the generation. I was born in the 1990's so I always thought it was pong. No. I discovered more than just pong, however simple it was, it wasn't the first game made. Pong was the first game to be imported onto a home console and when looking into this, its aparent that at this time, pong was a big deal.
Depending on the generation, the first game is always debated but we have the think about how it all began. Computers have been developing a long time before it was decided to make games using this.
Thier was about 20 million pong consoles with variations and released throughout the world. Just for pong. Is that really needed? Well at the time, game companies took advantage of this outstanding yet simple game. Today we have 3 game consoles to chose from but throughout the development of games, gaming consoles were in as many number as the games themselves. Over the years this has developed and now we have 3 which companies can simply make the games for them.
Through the 1950' - 1980's Nintendo and atari were the biggest companies that dominated the circuit. Many came to overthrow them but failed or just drifted away. This ones I can remember are the comador and the odessy which became copies of the more successful franchises.
But how far back did it go? Well, a long time. But im going to concentrate on the first games that came out that weren't open to the public because of the technology being too young and unable to be mass produced. In 1952, A.S. Douglas wrote his PhD degree at the University of Cambridge on Human-Computer interraction. Douglas created the first graphical computer game - a version of Tic-Tac-Toe. William Higinbotham created the first video game ever in 1958. His game, called "Tennis for Two," was created and played on a Brookhaven National Laboratory oscilloscope. In 1962, Steve Russell invented spacewar.
So I was wrong about pong being the first game every made. But technology stretches even furthur back. Some people may think this isn't important but it is. This was the granddad of the gaming world. Without this, people wouldn't have had any games. But to be fair it would eventually have happened because that is the human way. To venture into areas not yet discovered.
But to think of it. Games were never suddenly decided to be fun and interactive but began as an experiment in human interaction. But due to patenting issues and no true information. This can be debated till the end of time. Their is no clear evidence. Different sources say different things. At the start of looking into this, I thought spacewar was the first game but this wasn't till 1962 so their is nothing written in stone so makes it hard to state who, where and what.
But without this dog eat dog ear of gaming, we would have progressed this far so I would reguard this as the most significant part of the gaming world.
