If you're like me, then you probably thought that Facebook practically invented the term "poke," a word they've adopted to mean, as best as I can describe, reaching out to someone on Facebook and offering them an informal "hello."
As it turns out though, the poke has been around much longer than I realized. This blog post on E-Consultancy filled in the details.
The poke was actually born in 1963 as a BASIC command. Both "PEEK" and "POKE" were used by programmers, POKE meaning to insert data into memory and PEEK meaning to read that data.
The POKE command was also available for 8-bit computer games as a cheat - finding the right POKE could boost your immunity, get you more ammo, etc. On Usenet, gamers would search for POKE commands for their fav games. Who knew?
The post also gives details on the history of "fingering", a word that also sounded inappropriate to me. Fascinating read, though - check it out.
