WoT is massive though. Maybe you just overlooked it. It's almost impressive you hadn't heard of it, considering how often it comes up.
All I'm saying is that in the UK, over the years that it was ongoing, it never cropped up even once. No mention on the news. No publicity. No showcasing in the school or public libraries that I went to. It just wasn't in the British public's mind. Meanwhile Harry Potter was everywhere. Amongst schoolkids, Lemony Snicket was very popular, as was Philip Pullman's
His Dark Materials. And the sheer amount of Discworld books meant that they were prominent (you notice when an entire row of a bookcase is taken up by one series).
Robert Jordan's death made no significant news in the UK. Terry Prachett's did. The posthumous release of Douglas Adams
And Another Thing... (completed by Eoin Colfer - another well-known fantasy writer in the UK), was quite well known in the UK, the last WoT book...
And don't get me started on popularity outside the Anglosphere.
So, no I'm not doubting that the WoT series is very popular in some places (and yes, it does seem to have sold well in the UK). But nowhere near everywhere.
And I'm sure a lot of fantasy writers have read at least some of it. But fantasy as a genre is much, much, much older than 1990.
Therefore to say it's
influenced all modern fantasy is poppycock.
The one author who inarguably has influenced
almost all modern fantasy is J.R.R. Tolkien, as stereotypes he made or fleshed out appear in much of it.
Plus, perhaps I've listed enough fantasy there to earn my 'fantasy book' chops that for whatever reason you seem so eager to show that I don't have.
Edit: and now you lot are saying that I'm either very young (not true) or have never spent time in a bookshop (not true). I don't know why you've decided to make this personal.
