In Chapter 1 of Beautiful Code, "A Regular Expression Matcher," by Brian Kernighan (an early draft of which appears on Princeton's site), he writes "[Regular expression] first appeared in a program setting in Ken Thompson’s version of the QED text editor in the mid-1960s. In 1967, Thompson applied for a patent on a mechanism for rapid text matching based on regular expressions. The patent was granted in 1971, one of the very first software patents [U.S. Patent 3,568,156, Text Matching Algorithm, March 2, 1971]." That patent is viewable online here.

It's not proof that this is the first program that actually had it, but it's a good pile of evidence. I would like to hear of any examples prior to QED (which some sources leave out, claiming ed as the first to have them). I went on a hunt for previous examples once (before giving a class on regular expressions for my company; I didn't want to make unfounded claims), but could find nothing earlier.

I've been buying these for my linux systems. They work great and take no configuration (Tested on Debian Stable/Testing, Ubuntu 12 and up).
