Why are there two Hunter x Hunter anime?
The 1999 series was made by Nippon Animation, directed by Kazuhiro Furuhashi, and aired on Fuji TV from October 16, 1999 to March 31, 2001: 62 episodes, covering a manga that had launched only the year before. When the television run ended, the manga had not. So the adaptation kept going where television could not: as home video. Three OVA series, 30 episodes in all, followed from 2002 to 2004, carrying the story through Greed Island. Then the animated Hunter x Hunter simply stopped, seven years before the second version began. There had been an even earlier screen version, too: a 26 minute pilot film by Studio Pierrot, shown on the 1998 Jump Super Anime Tour.
By 2011 the situation had inverted. A decade of manga now existed beyond the old stopping point, an entire generation of viewers had never seen the first series, and the OVAs had never been a broadcast event. The new production did not pick up where the old one left off. Announced on July 24, 2011, it was a complete reboot with no connection to the 1999 series: new studio, new director, new voice cast, and the story retold from the beginning.
HOW THE 2011 PRODUCTION DIFFERED

The second version's afterlifeThe 2011 series is the version the decade canonized. Polygon named it one of the best anime of the 2010s, Crunchyroll ranked it among the 25 best anime of the 2010s, and IGN listed it among the best anime series of the decade. The 1999 version survives alongside it as the first telling, complete with its OVA continuation, a separate production with its own cast and its own stopping point. Two anime exist because the manga outgrew the first one, then outwaited it: a story still being written in 2001 had to be filmed in pieces, and a story with a decade more behind it in 2011 could finally be filmed from the top.
