So, way back when I started the blog, I made the assertion that I believed that Christopher Strachey's Draughts was the first video game ever. My stance on that solidified as a result of watching Stuart Brown's (Ahoy) video essay on the subject of the definition of a "video game", and what, based on that definition, ought to be classified as the first "true" video game. Incidentally, I don't think you should really read those early posts - my writing and research was quite lazy. Putting multiple games in a single post was a mistake - a mistake I may potentially look to rectify in the near future.
I still agree with Ahoy's assessment that Draughts is the first true video game ever made. However, that's not a consensus opinion. Plenty of people would disagree with me. There's plenty of other takes on the "first video game", and games that predate Draughts that could be argued as the first. Some say it's OXO, others Tennis for Two, and some would even say Spacewar! or Pong is the first. Ralph Baer, of course, argued that his "Brown Box" that would become the Magnavox Odyssey was the first. Here in this article, I'm going to discuss those other contenders (except Pong and the Odyssey, because ignoring 25 years of prior history to them is absurd), and attempt to settle on a definite date for when the concept of the "video game" was born.
