If Eden the TV series was based on a book, the book could be older, but it isn't. It's also possible, but not likely, and not the case here, that a TV show could be a sensation long before the first episode comes out. I can't think of a time when this happened except for a prequel or sequel like Better Call Saul, where it was much awaited, but I'm sure there are instances of that occurring. Edit: from another comment, there's this, which came out in 1997 but isn't mentioned in the Wikipedia article for the TV series so I'm not sure it's related: https://en.m.wikipedia.org/wiki/Eden:_It%27s_an_Endless_World%21 https://en.m.wikipedia.org/wiki/Eden:_It%27s_an_Endless_Worl... There is a Manga mentioned in the article for the TV series but it came out the same year as the TV show.
