What they are these days is just one big commercial, but at least it wasn't always as bad as it's become in the last decade and a half.
[size=8pt]For one thing, you could distribute files (and ideas) more-or-less freely without some giant faceless, soulless corporation squashing you dead. Oh yeah, there were no Quitter, F*kbook, Fraudspace, *oogle etc. around to squash you dead. Matter of fact, anything of a graphical nature was made out of text characters. Spyware was there, but you'd have to do something pretty daft or have a pretty crappy system to become infected by it. "Friends" were people we knew personally, in the real world, often in our very hometowns; not words and pixels on a CRT or cell phone screen like they seem to be these days. "Texts" were what we called the user manuals that came with our software or equipment. There was no (or actually very little) SPAM activity polluting Usenet!
And did you know that in the early days (meaning: ARPANET's last dying gasps/NSFNET's coming of age) commercial use of the "Internets" (yes, that actually was a real term years ago!) was severely frowned upon? That's right, Amazon Network and E-Bay only came about as a result of the Gorefication of the networks.
I was fortunate enough to have had cut my teeth on this "proto-Internet" and even "proto-World-Wide-Web" just before the World Wide Web in its current form reared its ugly commercialised head (circa 1994-5.)
But all good things have to end at some point and this is the result. Show me one site these days that doesn't have the Quitter or F*kbook logo on it at some point, or that doesn't include Google Analytics javascript in its source code. Go ahead, I challenge you.
(Say, this is my 1024th post. Now there's a nice round binary number! ;o)
