– Phytonet networks were the only option before access to global internet
– Phytonet relied on BBS networks to exchange files and messages locally
– Messages and files were bundled and sent as a stream from town to town
– The introduction of the ARK program revolutionized file compression
– ARK could compress files by up to 50% or even more
– Compressing data to half its size could save telecom bills by 50%
– ARK became popular among BBS operators and users
– ARK was adapted to various platforms including Unix, Atari ST, Amiga, VAX, and IBM 370
– David Huffman’s 1952 paper on compression was highly influential
– Huffman’s paper solved a problem that had never been addressed before

05:32 ARC was a fast and efficient compression software that became the de facto standard.
– ARC was a c implementation of huffman’s algorithm for compressing and decompressing 8-bit computer files.
– ARC could compress files regardless of their content or language.
– ARC was not freely available but followed the shareware distribution method.
– The ARC program was improved upon by Phil Katz, who optimized it for the MS-DOS platform.

07:23 Phil copied the source code for arc to create PK ARC
– Phil released PK ARC, which was faster and cheaper than ARC
– The release of PK ARC impacted ARC’s revenues
– Sca software reached out to Phil for a licensing deal, which he refused
– Sca sued PKWARE for trademark copyright infringement
– The discovery phase revealed that Phil had largely copied the source code for ARC

09:14 PKWARE released PKZIP 1.0 with the new zip file format, which quickly became the new standard.
