GIF Patent Prepares to Expire
pajamacore writes "It's worth noting that 20 June 2003 is GIF Liberation Day, the day on which US Patent 4,558,302 expires. The patent describes the LZW compression algorithm used in .gif files. That said, maybe the prices of image editing applications will drop slightly when corporations don't have to pay fees to Unisys."

Ahh what I wouldn't give to be young and naive again...
NO CARRIER
Riiiight...Photoshop "price"...don't tell Senator Hatch that.

I'll always remember GIF for introducing me to a huge underground world of BBS porn when I was a kid.
I used to string a 50ft telephone cord from my family's computer into the nearest phone jack (in the kitchen) every night and download GIFs over zmodem at 2400baud. It's a wonder I could stay awake in school.
Since the day we upgraded from CGA to VGA (256 color!) graphics, I've been a sick sick puppy.
Thank you, GIF! You made it all possible.
I had a similar experience with ASCII art and a 300 baud modem...
You missed one:
5. Using a toothpick to undermine the foundations of the Adobe headquarters.
That'll show 'm.
What have you got against Adobe, anyway?
Be wary of any facts that confirm your opinion.
Ode to LZW Compression
Abe Lempel, Jacob Ziv and Terry Welch
Discovered a neat algorithm to squelch
CompuServe incorporated it into the GIF
Good programmers soon caught the drift
The format was published, free and open
Many useful things started to happen
Then Unisys Corp purchased the rights
And changed the terms on LZW overnight
The useful algorithm was off limits
Ransom to corporate greed and profits
On June 20, 2003, the LZW patent expired
Shame on Unisys for what has transpired
Someday Unisys books will be in arrears
While the ideas of LZW survive the years
