This year is 50th anniversary of RS-232 standard. Despite its age it is still used nowadays, and I work in company that has to deal with it.

So we have a half-serious idea to celebrate the exact day the standard was issued. Does anyone knows that date? Maybe someone has printed copy to look into?

Though this questions relates more to history than to electrical engineering, I think that this site is the best place to find people who might have an answer. I've asked this question on Superuser, it was closed as off-topic, but I was advised to ask here.

    \$\begingroup\$ Many people don't know that "RS" stands for "Recommended Standard", which implies its preliminary status. Nowadays it is called EIA-232, but I seem to be the only person who uses that name. \$\endgroup\$ – stevenvh Jan 31 '12 at 8:03

    \$\begingroup\$ @stevenvh no problem, my intention wasn't to fight for the attribution of the name; what I think is that RS-232 is so popular among users that probably the newest name will be used only by a few people; somehow the same reason why you say Wi-Fi instead 8f 802.11/whatever \$\endgroup\$ – clabacchio Jan 31 '12 at 9:12

    \$\begingroup\$ I wrote TIA and they're considering incorporating this into their annual event this year, TIA2012. Still looking for the actual date.... \$\endgroup\$ – nealmcb Feb 2 '12 at 16:48

    \$\begingroup\$ I got an interesting, tentative response from TIA, suggesting that while the connector was introduced in 1962, the original EIA-232 Standard was published in 1960. It looks like in May of that year. Does that make sense?
