It was already common then, I gather—the ex-developer-product-owner guy who showed it to me (in the course of doing something else) didn’t seem to think it was remarkable, just an assumed capability. I don’t recall the name of the product, but it’d record all the input and page content for an entire session, you could watch it play back like a video. Exactly like standing over someone’s shoulder while they used their computer. Creepy as fuck, but some genius renamed “spyware” to “telemetry” and that was enough to get every developer on board because we’re super insecure and will jump at the chance to pretend we’re building Mars rovers or something else real while we make yet another “app” the world doesn’t need (I suppose that’s why that label was so successful at changing attitudes, anyway)
