2007: The Fox News reportage on 4chan (hackers on steroids), Rickrolling being conceived as a meme and Gurren Lagann, Lucky Star, Clannad, Kaiji, Kodomo no Jikan, Baccano, Minami-ke, Sayonara Zetsubou Sensei, Moetan, Potemayo, School Days, Bokurano, Claymore, Nodame Cantabile, Darker than Black, Gundam 00, Devil May Cry, Denno Coil, Mononoke, 5cm per second, Kara no Kyoukai, Eva 1.0 and Hidamari Sketch airing. Gurren Lagann was huge on /b/ at the time with the ROW ROW FIGHT THE POWER memes and stuff. Katawa Shoujo was also apparently conceived as an idea on /a/ in this year. This is when I started using imageboards. I can't go back further than this.
2008: The channology crap, the creation of /jp/ as the sewed off conjoined twin of /a/, GEASS SUNDAYS, Spice and Wolf, Rosario + Vampire, To Love Ru, Kannagi, Toradora, Chi's Sweet Home, Strike Witches, Hyakko, Soul Eater, Jigoku Shoujo, Chaos;Head, Ga-Rei-Zero, xxxHOLiC, Detroit Metal City, Kissxsis, Macross Frontier, Gurren Lagann movie and Index airing. This is when I first started using /a/.
2009: The Boxxy shit on /b/, Bakemonogatari, Umineko, Railgun, Redline, K-ON, Saki, Sengoku Basara, Kimi ni Todoke, Maria Holic, Sora no Otoshimono, Seiken no Blacksmith (the infamous katana gif), Kämpfer, Nyan Koi, Tokyo Magnitude 8.0, Fairy Tail, FMAB, Hetalia, Redline, Gurren Lagann movie, KnK 7, Eva 2.0 and Haruhi S2 airing. Also the Lanced Jack/Taiga mass shitposting on /a/ and /v/ which culminated in moot changing everyone's names to Lanced Jack and Taiga on /a/ and leaking Lanced Jack's tripcode. Very chaotic year.
2010: Nothing special happens that I can recall. Oreimo, Amagami SS, Angel Beats, Durara, Soremachi, Nyaruko, Arawaka, Seitokai Yakuindomo, Panty & Stocking, Ika Musume, Shiru Sekai, Sora no Woto, Bakuman, Tatami Galaxy, Katanagatari, Heroman, Shiki, Yosuga no Sora, Kiss×sis, Highschool of the Dead, Mitsudomoe, Heartcatch Precure, Milky Holmes, Eden of the East and Haruhi movie airs. Boring year.
2011: Madoka, Yuru Yuri, Nichijou, Usagi Drop, Steins;Gate, Fate/Zero, Carnival Phantasm, Deadman Wonderland, Mirai Nikki, Kaiji S2, Denpa Onna, Hanasaku Iroha, Hyouge Mono, Chihayafuru, Gosick, Guilty Crown, Penguindrum, Haganai,
[email protected], Anohana, Kore wa Zombie, Dog Days, Majikoi, Fate UBW movie and Infinite Stratos airing and Watamote becoming popular on /a/ and /v/, perhaps resulting in the anime adaptation later. Also, galo sengen, fukkireta, constanza.jpg, gachimuchi, etc happening on /v/ at the time. This is a year most /v/ users remember fondly. /pol/ is also made in this year after the deletion of /new/. This is when I started actually using /jp/, I would just occasionally lurk it before.
2012: Katawa Shoujo is released. Sword Art Online airs, popularizing the crappy isekai genre in that style. Girls und Panzer, OniAi, Little Busters, Medaka Box, Chunibyo, Hyouka, Another, Jinrui wa Suitai, Kill Me Baby, Acchi Kocchi, Accel World, High School DxD, Teekyu, Moretsu Pirates, Wolf Children, Eva 3.0, Nichibros, Symphogear, Magi, Mysterious Girlfriend X, Psycho-Pass, Shinsekai yori, Robotics;Notes, Upotte, Joshiraku, Kokoro Connect, Jormungand, Pet na Kanojo, Berserk movie, Muv-Luv Alternative and Jojo also airs.
2013: The downfall of /a/ and /jp/. /jp/ is splintered into numerous different spinoffs and moot destroys /a/ with N/a/ruto. He also told everyone at the 13th anniversary panel that /jp/ was "the new /b/" and for everyone to go post there, resulting in the board title being changed into "Weaponized /a/" and then "MISUNDERSTOOD GENUISES". I guess he was pissed at the shitposting happening there and the users constantly challenging and insulting him every time he went there. Other boards such as /mu/ also go to shit in this year. 13 is the bad luck number after all. Love Live, SnK, Kill la Kill, Inferno Cop, Nagi no Asukara, Valvrave, Golden Time, Yahari, Non Non Biyori, Kin-iro Mosaic, Prisma Illya, Date A Live, Log Horizon, Yuyushiki, Love Lab, Strike the Blood, Machine-Doll, Samurai Flamenco, GJ bu, Kotoura-san, Garden of Words, The Wind Rises, Little Witch Academia, Madoka Rebellion, Sasami-san, Hentai Ouji, Noucome, Watamote, Tamako Market, Kyokai no Kanata and Free! airs (this one caused a huge meltdown on /a/ at the time from KyoAni moefags).
