BSD 1 was released in 1978, and was itself a derivative of Unix 1 released in 1971 and started in 1969.
BSD derived works (including parts of MacOS, Windows and GNU/Linux, and numerous embedded devices like routers etc.) are still going strong today.
Most of the code will have been gradually replaced over such a long time, but there are libraries which can trace a lineage that far back. libc and libm come to mind.
Quite a few well known, non-trivial applications still used today were, perhaps surprisingly, first released in the 1970s. Examples: grep, diff, cron, awk, make.
