History — How Cathode‑Ray Tube Day Began
The idea of dedicating a day to cathode‑ray tube (CRT) technology emerged in 2018. A small online community of vintage electronics fans and retro computing hobbyists — calling themselves the Retro Display Society (RDS) — proposed that a day should be set aside to pay homage to CRTs, which by then had nearly vanished from mainstream use. The motive was simple: as flat panels (LCD, LED, OLED) replaced CRT monitors and televisions, the unique visual character and historical importance of cathode‑ray tubes risked being forgotten.
After deliberation and a poll among community members, May 22 was unanimously chosen — in honour of the date (May 22, 1922) when early experimental cathode‑ray tubes were first used to project live images in a scientific demonstration (though not yet for broadcast television). The inaugural Cathode‑Ray Tube Day was celebrated on May 22, 2019, when RDS members streamed live video restoration sessions, shared vintage TV commercials, and posted stories about early computing experiences on CRT monitors. Since then, the day has grown — slowly but steadily — into a recurring informal commemoration observed by retro‑tech fans worldwide.
Importance of the Day — Why Cathode‑Ray Tube Day Matters
Cathode‑Ray Tube Day plays a vital role in acknowledging technological heritage. CRT was the primary display technology for nearly a century — it powered televisions, computer monitors, oscilloscopes, radar displays, and many other devices. Without CRT, the golden age of black‑and‑white television, early color broadcasts, and the early days of personal computers might never have taken off so widely.
-
Preservation of Display Heritage: CRTs produced distinctive image qualities — high contrast, deep blacks, subtle colour gradations, and even analog scan lines — that defined how people experienced media for decades. Celebrating CRT helps preserve that aesthetic and reminds newer generations of how screen‑based visuals once looked.
-
Historical Reflection: By reflecting on CRT’s journey — from bulky vacuum tubes to obsolescence — we recognize the rapid pace of technological change. It encourages us to value technological transitions and to examine how newer innovations build upon older foundations.
-
Sustainability & Reuse Awareness: Many CRT sets still exist in basements, junkyards, or second‑hand markets. The day encourages thoughtful reuse, recycling, and safe disposal — rather than reckless e‑waste dumping.
-
Community and Culture Building: It brings together collectors, restorers, historians, and everyday users who share memories, technical know‑how, and nostalgia — strengthening bonds across generations.
When is Cathode‑Ray Tube Day Celebrated — And Why December 20?
Cathode‑Ray Tube Day is celebrated annually on December 20. This date was selected by the founding community (the RDS) in 2018 to mark an important early demonstration of cathode‑ray tube projection in 1922. Though CRT-based television and monitors became widespread later, this symbolic date acknowledges the technological birth of CRT visualization.
Choosing a date tied to the earliest documented CRT demonstration gives the celebration a deeper historical grounding — highlighting not just the commercial or entertainment use, but the scientific roots of cathode‑ray technology.
