To add to this, I have always found the Xbox naming conventions to be confusing, personally. "Xbox One" is the third one, not the original "Xbox" and the two newest models are named almost identically; "Xbox Series X" vs "Xbox Series S".
So from oldest to newest it's
- Xbox
- Xbox 360
- Xbox One
- Xbox One S
- Xbox One X
So for a period of time in stores you might see a One S, a One X, a Series S, and a Series X. If you aren't a gamer, it's a complete mystery which is the newest and most powerful. I'm sure some kids got the wrong console for Christmas, as the One X was at times more expensive than a Series S, despite being an older console that would later not support many games that the Series S supports. This would be even more likely to happen if the Series X was out of stock (so the most expensive Xbox console at the store might be a discontinued model that won't support all the new games.)
In contrast, it's pretty obvious that a PlayStation 5 is going to be better than a PlayStation 4. Yes, a quick search will show which is the newest and most powerful Xbox, but if people have to do research to find out which is your best console and they don't have to do that for your competitor, then you have a confusing naming scheme.
Sometimes I joke about how confusing the xbox names are. I probably couldn't come up with a more confusing set of names if I tried.
While officially the meaning of the "Xbox One" name was something about it being an all-in-one entertainment system, I would put money on it being chosen as some kind of subliminal naming scheme as it sounds like "Xbox Won".
I always judge corporations whenever they resort to "One" as a brand because it signals a total lack of creativity and is likely the result of executives fighting each other and settling on the most mundane and inoffensive concept to represent "it does everything".
