Lou Montulli, a former engineer with Netscape, writes about the origins of the blink tag. It seems that it was a lament for the lack of features in text-based browsers.
Back in 1994 I was a founding engineer at Netscape, prior to that I had written the Lynx browser, which predated all of the other popular browsers at that time. Lynx had been and still is a text only browser and is commonly used in a console window on UNIX machines.
Sometime in late summer I took a break with some of the other engineers and went to a local bar on Castro street in Mountain View. At some point in the evening I mentioned that it was sad that Lynx was not going to be able to display many of the HTML extensions that we were proposing, I also pointed out that the only text style that Lynx could exploit given its environment was blinking text. We had a pretty good laugh at the thought of blinking text, and talked about blinking this and that and how absurd the whole thing would be.
Saturday morning rolled around and I headed into the office only to find what else but, blinking text. It was on the screen blinking in all its glory, and in the browser. How could this be, you might ask? It turns out that one of the engineers liked my idea so much that he left the bar sometime past midnight, returned to the office and implemented the blink tag overnight. He was still there in the morning and quite proud of it.
Why am I not surprised that the idea originated in a bar.
