Popular anime that were forgotten over time

In the comments of a forum, fans were excitedly debating certain forgotten anime that were once giants in the industry, but over time lost relevance in the conversations.

The question raised by one user sparked a deep reflection on the changing dynamics of the otaku community and how interests shift to the latest trends. "Which anime have completely fallen into irrelevance?"

I'm very interested in series that used to be industry giants, but now their presence in the conversation is barely a whisper. What are some anime that have completely fallen into irrelevance as time has passed? ", asked the user.

This question triggered a series of varied responses, where participants reflected on how certain anime, which once dominated the scene and captured the public's attention, were gradually forgotten or relegated to the background.

Some users pointed out that the ephemeral nature of the entertainment industry can cause even the biggest hits to eventually fade into oblivion, eclipsed by new ideas and trends. Others cited market saturation and media overexposure as factors that may contribute to the decline in relevance of certain anime over time.

Check out all the comments:

Tokyo Ghoul? I agree, a lot of it is due to the final season being a disaster, but even so, it used to be one of the best animes, on par with SAO, Death Note, Code Geass, etc. Now people are doing everything they can to forget it.
Noragami. It was big, but it faded away, mainly because there wasn't a third season. I'd say Blue Exorcist, but it came back from the dead.
Haruhi and Shakugan no Shana come to mind. Haruhi had a great first season; it was everywhere. People who hadn't seen it were actually tired of seeing it on the forums (yes, that was back then). Shana was the quintessential tsundere. People adored her. Both series are now so irrelevant that mentioning them can elicit a "...huh?" from younger or newer fans. Haruhi still has a certain reputation, but I rarely see it mentioned online.
I'd forgotten Magi existed until about two weeks ago. It used to be huge.
Love Hina was a huge hit 20 years ago, as it was the archetype of ecchi harem anime at its peak. As the genre fell out of favor, it became a footnote.
A Certain Magical Index was a hit when it premiered in 2008. If you ask anime fans under 25, like my sister, if they know it, they probably don't.

So other fans have highlighted more forgotten anime:

Before Sword Art Online, Log Horizon, and all those 'trapped in a game' series, there was the .hack series, in particular .hack//Sign.
Log Horizon. It was very popular, then the creator got involved in a tax fraud scandal, I believe, and disappeared for a LONG time. It came back... to mixed reviews, and then just... disappeared.
I don't see Ah! My Goddess. Beldandy used to be a top-notch waifu back in the day.
Deadman Wonderland.
Haruhi Suzumiya is nowhere near as big as it was in the mid-2000s.
Lucky Star. A classic that seems to fall further into irrelevance with each passing day.
Who still remembers D. Gray Man?
Elfen Lied and Mirai Nikki were quite notable and controversial series when they were released, but nowadays they are hardly talked about.
I haven't heard Escaflowne's name since the 90s, even though I was in that big first wave.
Soul Eater

Finally, it's time to find out which forgotten animes you have on your list.
