Every one of these was, at some point, a genuinely important part of how people used the internet. All of them are gone now, in one form or another — and a surprising number of them are mourned with real, specific nostalgia rather than just vague recognition.
Google Reader (2005–2013)
An RSS feed reader that let users follow updates from blogs and news sites in one clean, organized place. When Google announced it was shutting down in March 2013, effective July 1, a petition to save it gathered tens of thousands of signatures within days — a level of public outcry that remains something of a benchmark for how attached people can get to a piece of infrastructure software.
Vine (2013–2017)
A short-form video app built entirely around six-second, looping clips, Vine helped launch an entire generation of early internet comedians before Twitter, which owned it, shut it down in January 2017. Its influence on short-form video culture is still visible in everything that followed it.
iGoogle (2005–2013)
A customizable personal homepage from Google, letting users arrange widgets for weather, news, and email into their own dashboard. It was discontinued in November 2013 as Google consolidated its products, a casualty of a broader shift away from customizable portal-style homepages.
Google+ (2011–2019)
Google's attempt at a Facebook competitor never achieved anything close to Facebook's cultural relevance, but it built a genuine, devoted niche following, particularly among photographers and tech enthusiasts who liked its features. Google announced its shutdown for consumers in October 2018, following a data exposure issue, with the consumer version fully discontinued in April 2019.
AOL Instant Messenger (1997–2017)
AIM defined instant messaging for an entire generation before texting and smartphone apps made it redundant. AOL kept it running in a diminished state for years after its cultural peak before finally shutting it down on December 15, 2017 — twenty years after launch.
Friendster (2002–2015 as a social network)
One of the first mainstream social networks, Friendster grew explosively in the early 2000s before losing users to MySpace and later Facebook. It relaunched as a gaming platform for a time before shutting down entirely, but its early influence on how "friends" and profiles worked online is still traceable in the networks that outlived it.
GeoCities (1994–2009)
The free-hosting service that let millions of people build their first personal website was shut down by Yahoo in October 2009, deleting the vast majority of its user pages in one stroke. Volunteer archivists managed to preserve a large portion of it before the deadline, which is the only reason so much of it is still browsable today.
Yahoo Answers (2005–2021)
A crowdsourced question-and-answer site, equally beloved for genuinely helpful advice and mocked for its bizarre, low-effort questions and answers, Yahoo Answers shut down in 2021 after 16 years — closing out an internet institution that had become as much a meme as a resource.
What links most of these isn't necessarily that they were the biggest or most important sites of their eras. It's that each one occupied a very specific daily habit — checking feeds, watching six-second clips, managing a customized homepage, seeing who was online — and once that habit lost its home, there often wasn't a clean replacement that felt exactly the same.
Why some shutdowns sting more than others
Not every closure generates the same reaction, and the difference seems to come down to whether a replacement genuinely covers the same ground. Facebook absorbed most of what Google+ tried to do, so its shutdown barely registered outside a small dedicated user base. But nothing quite replicated Google Reader's specific combination of control and simplicity, and nothing fully replaced the particular six-second comedic format Vine popularized, which is why both still come up regularly in conversations about apps people wish they could get back, years after they disappeared.
