Long before Tumblr, wikis were the ultimate hub for cult TV fans to dive deep into their obsessions. These community-driven databases, built and maintained by fellow enthusiasts, offer a treasure trove of trivia, lore, and behind-the-scenes details—though always cross-check for accuracy amid the fan passion.
As a lifelong TV aficionado with years exploring these sites, I've seen how they capture the collective knowledge of fans who share your devotion. They're perfect for uncovering hidden facts about your favorite shows. Let's explore some standout wikis.

No cult series commands more devotion than Doctor Who. Celebrating its 50th anniversary last year, this timeless sci-fi epic—starting with William Hartnell as the first Doctor—remains as captivating as that foggy junkyard TARDIS debut on Totter's Lane.
The TARDIS Data Core wiki punches above its simple exterior. It's structured into key sections: In-Universe (fictional lore), Real World (actors, production history), Non-DWU (non-canon works like games and The Curse of Fatal Death), and The Hub (wiki mechanics). All roads lead to 'Floor 500,' a nod to the 2005 episode The Long Game, the heart of its knowledge base.
Crucially, it avoids spoilers, focusing on past events. For more, check global Doctor Who sites—after 50+ years, options abound, including top lists and 50th anniversary apps.

Game of Thrones isn't just a hit—it's a phenomenon. Since 2011, HBO's adaptation of George R.R. Martin's A Song of Ice and Fire novels has exploded in popularity, filling bookstores worldwide with its epic tomes.
The Game of Thrones Wiki boasts nearly 2,500 pages on episodes, characters, and production. Fan passion shines through, with latest episodes featured left, upcoming ones right—balancing past, present, and future.
The books' dedicated wiki, started in 2008, dives into 1.77 million words of source material. Spoiler warning for future seasons! Tips for dodging social media spoilers can help. With HBO greenlighting more seasons, Westeros endures.

“It’s not as good as it used to be,” critics say. Yet classics like Whacking Day, Deep Space Homer, You Only Move Twice, and Behind the Laughter keep Homer, Marge, Bart, Lisa, and Maggie smiling through.
This wiki relives iconic lines—“My eyes! The goggles do nothing!”; “You'll have to speak louder. I'm wearing a towel”; “Hello, Lisa. I'm Super Nintendo Chalmers”—plus Springfield spots: Kwik-E-Mart, Leftorium, even gag locales like Uncle Moe's Family Feedbag or 123 Fake Street. It covers the 2007 film, comics, and Tapped Out app too. It embiggens the smallest fan.

Though smaller, this wiki thrives post-2010 finale. Life on Mars and sequel Ashes to Ashes—from Matthew Graham and Ashley Pharoah—dazzled with John Simm (Sam Tyler), Keeley Hawes (Alex Drake), and Philip Glenister (Gene Hunt). It influenced culture, even UK elections evoking 1980s riots.
Covering UK series and the less-successful US remake (no Tonight by Bowie), its retro design evokes the shows' Quattro era vibe.
These wikis scratch the surface of cult TV love—sci-fi gems await too. What's your top show and wiki, and why?
