Set in the late '90s & early/mid 2000s
Anime
A stack of animes which are set, fully or partially, in the late'90s and early-to-mid 2000s, so somewhere between 1997 and 2007, roughly.
Most of these animes share the same nostalgic vibe for that era and naturally replace smartphones with old mobile phones, modern computers with white CRT monitors and Internet Explorer, and the flashy colorful and dynamic cities of today with the grayer, blocky feeling of this era.

The first and third parts are partially set in the mid-to-late '90s. The third part stresses this era, drawing comparisons of it with modern times. Cassette tapes, radios and the old buildings of Shanghai pave the way to nostalgia for a now long-gone, simpler time.

Set in 1998, the thing that resembles the modern digital era the most here is probably those blocky portable phones some characters have. Another screams nostalgia with its now-antique setting.

Set in 2003, Clannad is filled with the nostalgia of the bygone early and mid 2000s. VHS tapes, those big boxy TVs, talking on your home phone, CDs and cassettes. Face-to-face interaction being the only way to meet with your friends, and the small yet changing towns of old. Just a whole lot of melancholy.

Set in 2006 and early 2007. White CRT monitors, blocky cameras, watching anime on cable TV, flip phones, PlayStation 2 and Suzumiya Haruhi references. The good old days before we all turned into slaves to the algorithms.

Set somewhere between 2002 and 2006. Windows XP, Internet Explorer, websites built on basic HTML, digital cameras... ah, yes, the early 2000s alright. This anime is a one-way nostalgia trip.

Set in around 2002. Apart from the minor sci-fi elements, this anime exudes the simplicity of a time in which computers, phones and all other digital stuff were rare, and in the case of this anime, pretty much nowhere to be seen.

Set roughly between 1999 and 2002. Many scenes are extremely nostalgic, such as seeing the teachers driving old sedan cars, the characters speaking on home phones, using the early internet on CRT monitors, or standing in the middle of Tokyo next to a store which sells CDs and DVDs. This is a time capsule.
