Acronym. Also written public service announcement.
Where it comes from
Borrowed from broadcast public service announcements. Online it lost the official connotation almost entirely and became a way of marking any post as useful rather than personal.
How it is actually used
Now used with a wide range of seriousness, from genuine warnings to jokes about trivial annoyances. The mock-official register is much of the appeal. For brands it is a useful frame for outage notices and deadline reminders, where the tone signals "this affects you" without alarm.
Examples
- "PSA: the API version sunsets Friday"
- "PSA that this shortcut exists"
- "PSA: it is not a bug, it is a setting"
Can a brand use it? Safe for brands
Safe and well suited to status and deadline posts. Reserve it for things that genuinely affect the reader — a PSA about your own promotion reads as a marketing message wearing a hat.
