Remember ICQ? After almost three decades, the once-popular instant messaging client is finally shutting down. 

On Friday, the ICQ website posted a simple message: "ICQ will stop working from June 26." It now recommends users migrate to the messaging platforms from VK, the Russian social media company that acquired ICQ from AOL in 2010, but under a different corporate name. 

It's an unceremonious end for a software program that helped kick off instant messaging on PCs in the 1990s. ICQ, which stands for "I Seek You," was originally developed at an Israeli company called Mirabilis before AOL bought it in 1998 for $407 million.

ICQ, which was released several months before AOL's own instant messenger, had 100 million registered users in 2001. But over time, ICQ lost out to competing instant messengers and smartphone chat apps. In 2010, VK bought ICQ with the goal of revitalizing it since the instant messaging app had been quite popular in Russia. 

VK developed mobile versions of ICQ, which helped the client grow in 2014. But following several attempts to modernize the software, the app’s development has sputtered. Both the iOS and Android versions were retired from the App Store and Google Play, according to Techspot.

VK didn’t respond to a request for comment. But the ICQ shutdown suggests the company would rather retire the app than continue spending money on it. VK operates a Facebook-like social media platform, along with VK Messenger, which has over 10 million downloads on Google Play. Still, the X/Twitter account for ICQ is teasing a comeback in some form.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
