There is a piece of lost media many people in Germany are looking for. Unfortunately, no one in the German lost media community found it so far. Probably whoever out there happens to have it doesn't know it is sought after.
This piece of lost media is a YouTube video that had a medium six-digit view count, from a channel that had almost half a million subscribers at the time it was released, and now has over a million subscribers, so there is a realistic chance someone out there has preserved it.
An idea in the back of my mind was to ask for it through the Internet megaphone: a search engine advertisement.
Someone searching for specific terms would get an advertisement that asks them if they have a copy of said video.
The advertisement could look similar to this:
Do you have a copy of "[video title]" by "[creator]"?
or
We are looking for the video "[video title]" by "[creator]". Please send us a copy if you have it.
Followed by contact details.
Given that this piece of lost media is a YouTube video, I highly doubt Google would allow it to be advertised on their platform because , nor do I trust Google with my real-life identity (which they require advertisers to disclose).
Therefore, I would have to resort to alternatives like Bing and DuckDuckGo. DuckDuckGo loads advertisements from Bing from what I understand.
Do you have experience asking for lost media through search engine ads? Do you recommend it? How do you imagine such an ad would look like?
