A better question to start would be if there's any creative commons or copyleft media in the modern zeitgeist.

Memes are made organically as small units of culture and gain popularity via an implicit understanding of meaning that doesn't need to be explained.

For a meme template to have those attributes, it would need to derive from a work that was licensed as CC/copyleft from the get-go and gained popularity among the masses.

That being said, seems a moot point when fair use/derivative work standards allow unlicensed memes to legally exist regardless of the original licensing of the work they were derived from.

Idk, but if not that's a great idea. We could have Linus IRL posed photo "is this" memes and such!
