(1) and (2) developed an algorithm, that (3) later optimized and patented. (3)’s patent was granted in the name of Sperry Corporation (that later, through a series of unfortunate events, became Unisys). The company X, unaware of the patent, chose this technique to implement their famous format Y.

X, however, went nuts and decided to require everyone who used Y to pay them (and Unisys) money for using their format. This caused much IT industry uproar and melodrama that went against X and, some believe, eventually lead to X’s downfall.

Now, identify 1, 2, 3 and name the company X and the format Y.

1: Lempel
2: Ziv
3: Welch

The LZW compression algo is named after these people.

X: CompuServe
y: GIF (uses LZW compression)

  1. udupendra

    Lempel, Ziv, Welch, Compuserve, GIF. Too simple :(

  2. pratap

    Lempel, Ziv, Terry Welch, Compuserve and the GIF format

  3. madhur

    1. Abraham Lempel
    2. Jacob Ziv
    3. Terry A. Welch
    LZW data compression algorithm was developed by Abraham Lempel, Jacob Ziv and Terry A. Welch

    LZW was published by Terry Welch as an improved implementation of the LZ78 algorithm published by Lempel and Ziv

    X is CompuServe Inc. and format Y is GIF

    1 –> Lempel
    2 –> Ziv
    3 –> Welch
    X –> CompuServe
    Y –> GIF

  6. Shakeel

    1)Abraham Lempel
    2) Jacob Ziv
    3)Terry Welch

    2. Jacob Ziv
    3. Terry Welch

    X: CompuServe
    Y: GIF

  8. piezocake

    LZW compression, GIF patent, I’m guessing.

  9. Keerthi Kiran M

    1. Abraham Lempel
    2. Jacob Ziv
    3. Terry Welch
    Developed: lossless LZW compression algorithm
    Clue: “Burn All GIFs” campaign against lincencing of GIF

  10. shivathilak

    1) Abraham Lempel
    2) Jacob Ziv
    3) Terry Welch
    4) IBM
    5) GIF format

  11. RajT

    1,2,3 = Abraham Lempel, Jacob Liv, Terry Welch

    X = CompuServe

    Y = Graphics Interchange Format (GIF)

  12. Abraham Lempel, Jacob Ziv, and Terry Welch

  13. yaksha

    Abraham Lempel, Jacob Ziv, Terry Welch-LZW algorithm

  14. 1) Abraham lempel
    2)Jacob ziv
    3) Terry welch
    X – Compuserve
    Y – Lempel-Ziv-Welch LZW format which is a part of the GIF format

  15. nishansolo

    1. Jacob Ziv.
    2. Abraham Lempel.
    3. Terry Welch.
    X – CompuServe.
    Y – LZW Data Compression Algorithm.

  16. After hellacious wiking
    1=Abraham Lempel
    2=Jacob Ziv
    3=Terry Welch(Couldn find his pic,hope am not googlied!)
    y=GIF format

    The point in essence must go to Wikipedia!

  17. Ganesh Prasad

    (1)Abraham Lepel along with (2)Jacob Ziv presented the LZ77 algorithm – a universal lossless data compression algorithm
    (3)Terry Welch invents a derivative of LZ78 which was called LZW(Lepel-Ziv-Welch)
    Company Compuserve(X) in 1987 released a new graphics file format called GIF (Graphics Interchange Format)(Y) where the graphics data is compressed with LZW.

  18. Tathagata Chatterjee

    1)Jacob Viz
    2) Abraham Lempel
    3) Terry Welch
    X= Compuserve
    Y= GIF ( Graphics Interchange Format)
