I've seen a number of discussions in various places about the "lifespan" of editions. I worked up the timespans, and thought I'd share it since I already did the work.
Discussing editions has a lot of gray areas. Is 3.5 a different edition from 3E? Does the 2nd edition "Skills & Powers" era count as a separate edition? How does BD&D fit in?
I decided to completely ignore BD&D because the versions were concurrent with the "main editions." I have two lists of lifespans after that. The first has the most restrictive definition of edition. The second has a very permissive one, and might even be better called the "D&D era" version.
Limiting things as much as possible, though, we have:
OD&D (1973-1977*) 4-6 years
AD&D (1977**-1989) 10-12 years
AD&D 2nd edition (1989-2000) 11 years
D&D 3E (2000-2008) 8 years
D&D 4E (2008-?) TBD
The most permissive has:
"Pure" OD&D (1973-1975) 2 years
OD&D + Expansions (1975-1977*) 2 years
AD&D (1977**-1985) 8 years
AD&D + Unearthed Arcana (1985-1989) 4 years
AD&D 2nd edition (1989-1995) 6 years
AD&D 2nd edition "Skills & Powers" (1995-2000) 5 years
AD&D 3E (2000-2003) 3 years
AD&D 3.5 (2003-2008) 5 years
* 1977 is not a hard end date, since D&D material was released at the same time AD&D material was and see the next footnote.
** 1977 is a vague start date. The AD&D Monster Manual was released in 1977, but the DMG wasn't released until 1979. PHB was 1978 which might be the fairest choice.
*** Yes, there are still people playing every edition, including OD&D. Saying the OD&D era is still going isn't a very productive definition for comparison.
