I don’t think Grace Jones was ever hugely successful, and I also don’t think she’s completely forgotten.
None of her albums ever made the US top 30 and none of her singles made it past number 69. Granted, she had a top 10 album and a few top twenty singles in the UK, but she was hardly “hugely successful”.
But her work as a model and fashion pioneer is the reason I’d argue she’s also not completely forgotten today, Grace Jones is a big influence on fashion these days - seen Lady Gaga lately?
Transformers is not only not forgotten, but was recently made into two very successful (and terrible) movies. A third Transformers movie is in the works, and will presumably be equally successful (and terrible).
I also have a hard time believing that Pac-man is forgotten. Google recently put a Pac-man game on its main search page to celebrate the game’s 30th anniversary.
(It can still be played here: 30th Anniversary of PAC-MAN .) I think Pac-man has achieved an iconic status. Even if nobody plays Pac-man ever again, the little yellow guy will be remembered for some time.
Ernest Hemingway and Norman Mailer. It’s relative, obviously, as neither is forgotten. But my impression is that both of them, at the peak of their popularity, had fame that goes beyond that of your usual best-selling author. I also have the impression that neither one has the sort of current reputation in academia that you might’ve expected.
Both made the Modern Library 100 Best Novels list, though. The Sun Also Rises is 45th, The Naked and the Dead is 51st, and A Farewell to Arms is 74th.
