I realize that the <isindex> tag came first, but which browser was the first to support the <input> tag and when?

    Hmm. It is really a "History of Computing" question. Considering that many history.se members are also participants in the computing stack exchanges, I think this question is reasonable if odd. Since answering it may require digging through reams of old RFC spec releases, I wouldn't consider it trivial but possibly too hard to answer? – LateralFractal Nov 15 '13 at 1:49
  • I saw the question through meta review pane which didn't show the answers. Apparently it is easy to answer :-) – LateralFractal Nov 15 '13 at 1:56

    Should we move this question to "Programming?" SE. It's technically history, but a specialized topic that might be better answered by others in this specialty. – Tom Au Nov 15 '13 at 22:46
  • I agree with @LateralFractal. We see a lot of questions on Academia.se that have mostly to do with computing but since there's so much crossover they usually get answered. – Dave Kanter Aug 3 '16 at 16:26

The <input> tag is a part of HTML forms, which first appeared in the Mosaic browser in April 1993. It was standardized in HTML2 in November 1995.


The input tag is part of HTML and as such not an "add on" that just one browser would have used/supported. According to this page, the input tag was a part of HTML2, which rolled out between 1995 and 1997. That would put it on Netscape Navigator and IE (IE 3 came out in 1996).
