No passive voice.
In the beginning, it all began with Ralph Baer in 1967 in Nashua, NH. In 1966, while working for Sanders Associates Inc., engineer Ralph Baer began to investigate how to play games on TV. (add examples of investigations, don't add too much cuz it is gonna get too wordy)And as a result of his investigations Brown Box was created. According to the G-Phoria Legend Award, “Baer is considered "the Father of Video Games due to his many contributions to games and helping to spark the video game industry in the latter half of the 20th century”. Little did we know this great invention would be in everyone's life today.
I would say you should tell the reader some of the investigations he made, possibly some examples.
