A way of sorting history
Home consoles are often described by generation: the third generation, the fifth, the eighth and so on. A generation is a group of competing systems that arrived within roughly the same period and were built with broadly similar technology. When a new group appears with a clear step up in capability, it is counted as the next generation.
The convention is useful because it lets people compare systems that were rivals at the time, rather than comparing machines separated by many years.
No official rulebook
There is no governing body that decides what counts as a generation. The numbering is a convention developed by writers, historians, fans and industry commentators, mostly after the fact. As a result:
- Numbering varies. Different sources may count from different starting points, for example whether the earliest home game systems are included.
- Boundaries are blurry. Systems released a year or two apart may be grouped differently depending on who is doing the grouping.
- Terms are applied backward. Companies at the time seldom used generation numbers, and people living in those years more often talked about bit ratings or simply the newest machine.
For this reason, if two sources disagree, it usually reflects different conventions rather than a factual error.
The usual cycle
Historically, major console makers have often released new hardware every five to seven years or so, although this is a tendency and not a rule. Several things push toward a cycle:
- Components improve over time, so a console designed several years earlier begins to look limited.
- A fresh release lets the manufacturer reset the competition and revive attention.
- Developers want access to more capable hardware to attempt more ambitious games.
- Manufacturing costs for older hardware typically fall, which gives makers room to introduce a new system.
Companies do not always release on the same schedule, which is how systems from the same generation sometimes appear at different times and why rivals can overlap awkwardly.
What typically changes
Each new generation has tended to bring some mixture of the following:
- More processing power, enabling more detailed graphics, bigger game worlds and more complex simulations. How a gaming computer works inside covers the parts involved, and consoles use similar types of components.
- Better graphics and displays, such as higher resolutions and smoother motion, which relate to screen resolution and frame rate.
- New media. Cartridges gave way to discs, and later to downloads, part of the wider shift in game media formats.
- New controllers and ways to play. Analog sticks, vibration, motion sensing and touch input each appeared at different points.
- Online features. Early consoles had none, and later systems added networking, accounts and storefronts.
- New business arrangements. Digital stores, subscriptions and updates changed what a console is for.
Not every item changes every time. Some generations were mostly about raw capability, and others focused on new ways of playing.
Mid-generation refreshes
In recent years, manufacturers have sometimes released improved versions of a console in the middle of a generation. These upgraded models can play the same games as the base model, often with better performance. Because the library is shared, they are normally considered part of the same generation rather than the start of a new one. This is one more reason why the line between generations is a matter of interpretation.
Handhelds and other categories
Handheld systems have often been counted on their own timelines, and sometimes in their own numbering, because their competition and hardware cycle differ from those of home machines. Hybrids that work both at home and on the move are difficult to place.
Why generations matter to players
Generations help set expectations. A new generation often means older games will look dated by comparison, and it can raise the question of whether a previous library will still be playable, which is the subject of backward compatibility. It also shapes how long a console remains supported with new games, since publishers eventually shift attention to the newer systems.
Treat the labels as shorthand. They help organize a long history, but the real picture includes overlapping release dates, regional differences and products that do not fit neatly into any group.
