Supply chain problems are starting to drag down growth in the PC market, particularly in North America. During Q3 2021, PC shipments to the US and Canada dropped by 9% compared to the same time period last year, according to research firm Canalys. 

IDC, another research firm, also reports a Q3 shipment decrease for the US, calling it the "first quarter of annual shipment decline since the beginning of the pandemic."

PC shipment growth numbers from Canalys

2020 was the biggest year for PC demand in a decade. However, a host of supply chain problems are preventing the electronics industry from meeting the continued demand. The world continues to grapple with an epic semiconductor shortage, and COVID-19 outbreaks are still shutting down factories in Asia. Meanwhile, both manufacturers and the shipping industry are struggling to retain and hire enough workers. 

None of this bodes well for the holiday shopping season. “​​The shortfall in supply of PCs is expected to last well into 2022, with the holiday season of this year set to see a significant portion of orders not met,” says Ishan Dutt, a senior analyst at Canalys.  

At the same time, spending on PCs seems to be dropping off in the US. “After a year of accelerated buying driven by the shift to remote work and learning, there’s also been a comparative slowdown in PC spending, and that has caused some softening of the US PC market today,” says IDC analyst Neha Mahajan. 

Still, PC shipments overall were actually up year over year by 5% according to Canalys. That’s because other regions, such as Latin America, Europe, the Middle East and Africa, and Asia, registered strong annual growth in the double digits. 

IDC also finds that overall PC market growth in Q3 was up 3.9%. “Given the current circumstances, we are seeing some vendors reprioritize shipments amongst various markets, allowing emerging markets to maintain growth momentum while some mature markets begin to slow,” says IDC analyst Jitesh Ubrani.

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.
