| "Everyone" very much didn't. Most of the people in my life have seen the movies. Relatively few have read the book even now. Most of those close to me who have read the books did so after the movies came out as a direct result of hearing about or seeing the movies. It wasn't obscure to fantasy fans, but very few fantasy books break through and sell well. Most genre fiction outside of romance, thrillers/crime sell ridiculously low numbers. In a 2003 interview, the project manager for Tolkien at Houghton Mifflin, who held the US rights, stated that they had at the time only had two million-copy bestsellers in the company's history: The Silmarillion in 1977, and LOTR in 2001 in the runup to the first movie. By 2003 they'd sold 2 million copies of the one-volume trade paperback in the US. Worldwide, combined sales went from 50 million copies in 2003, already massively boosted by the movies, to 150 million by 2007. In other words: Nearly half a century to get to 50 million, with a significant proportion of those 50 million in the last few years of that period, and then 100 million in the following 4 once the movies were well known. The readers of "any must read fantasy bookshelf" are a small enough demographic that if they were the only ones who'd watch the movies, they'd have bombed spectacularly. |
Those aren't the people that read fantasy in the first place. If they haven't "read the book even now", it's not like it matters that they seen the movies. For them it could be any other movie in their place, and they would be just as satisfied.
