Around 2005 digital cameras were commonplace. Mobile phones also had cameras by then, even if not very good ones by today's standards. Maybe you're talking about an earlier time?

2005 is pre iPhone. While cameras were definitely common, they also weren't quiet as ubiquitous as they're today. Lots of families only had them for trips etc, not readily available for kids to make photos of screens.

I hate how incompetent tech writing and marketing rewrote and simplified mobile phone history into pre/post-iphone. Yes, we did have touchscreens, smartphones and camera-enabled devices many years before the iPhone. Arguably, on several metrics, many Symbian/Linux/blackberry phones of that era are better smartphones than today's iPhone/Androids as defined by hardware capabilities which got removed over time while arbitrary constraints got added on the software front.

This was a nice trick to protect text from copying. For instance, student assignments. Students could still use digital camera on CRT display, but 20 years ago cameras were costly and students did not have them. And typing text from scratch was a tedious job. So online served assignments were not shared too fast.

I had my first digital camera in 2003 and my first videocall-capable phone in 2004 (Nec e313). I was a kid

> These special surfaces were called “overlays” because they appeared to overlay the desktop.

I have some vague memory of programs whose windows had funky shapes (i.e. not rectangular) also using overlays of some kind. Maybe that's a different sort of overlay?

Don't know about other markets but the first iPhone didn't sell well especially because it was behind the high end feature phones of the time for a more expensive price.

The iPhone which made it was the 3G.

"Nowadays, video rendering is no longer done with overlays." Darn, I thought this explained why, after upgrading my GPU, videos playing in Chrome have a thin green stripe on their right edge.

A green stripe on the right/bottom is usually due to a different issue: interpolation errors in chroma planes when decoding YCbCr video. The chroma planes use a biased encoding where 0 (no color) is mapped to 128. A sloppy YCbCr to RGB conversion without proper clamping can interpolate against 0 at edges, which is interpreted as max negative chroma red/blue -- which combined together produces green. This can happen either due to an incorrectly padded texture or failing to handle the special final sample case for 4:2:2 chroma.

This issue can happen with overlays, but also non-overlay GPU drawing or CPU conversion routines.

I made extensive use of this, when I found it by accident, in my Winamp skins and GUI programs!

I found this also by accident when I was kid and I used it as putting video as wallpaper for my desktop. I thought it was pretty cool.
