You used to be able to count the number of years between game consoles on one hand.
The original Sony PlayStation came out in the UK in September 1995. Five years later, the PS2 was released and brought with it significant changes.
It was a similar story for other consoles but, of late, things seem to have slowed down - which might explain why, as the PS5 hits its fifth anniversary, a potential PS6 is nowhere in sight.
According to PlayStation's business boss, Eric Lempel, that's because there's plenty of life in the old dog yet.
"I would say we're really hitting our stride now," he told BBC News.
