Brainstorm is a Swiss-based demo group, that has existed in two distinct periods; their formation as an Amiga demo group in the period between 1989 and 1993, and their reformation as a mainly pc demo group in 2006 until present day. They were originally formed a short while before may 1989 by graphician Chester and coder Majestic, and their first release was Lazer Roll. During the summer they recruited more members (like Orlando), and at the end of the summer vacation they were joined by the entire group Axxis (Bird, ...). This group had both a Swiss and German section, but the German section was found to be substandard and was forced to leave after a while. Another member, swapper Joker, left the scene soon after. They had by now started planning what would become the diskmagazine Zine. It was originally conceptuated as a cooperation between Brainstorm and another Swiss group at the time, Setrox, but the latter eventually decided against being part of the project. Due to this, Setrox coder The Accused left to join Brainstorm. Zine 1 was released in october. They were now a totally Swiss group again, except for two German members - Shadow and Yankee.

Advert in Cracker Journal 18 (january 1990), looking for members. Cracker Journal 19 (march 1990) reported, "Angel Dust joined Brainstorm and his name is now Six Pack." Sometime between Zine 3 (february 1990) and Zine 4 (april 1990) they decided to kick their German writer Yankee because he wasn't productive enough. He was a freelance writer for D.I.S.C. for a while before finally joining Addonic. Zine 5 was released at the Alcatraz Pentcost Party 1990 at the beginning of june. It was to be Orlando's last issue as editor, as The Accused had returned from his army service.

Metamorphosis (august 1991) mentioned their bbs Cheese-Line as 'new', and listed Accused, Axel, Bird, Chesney, Chester, Droid, ESA, Fly, Grubi, Luke, Macho, Majestic, Odie, Oli, Orlando, Patsy, Peace, Scattergold and Truxton as active members. Danish megaswapper The Pride joined the group in late september, and was sent a new packmenu for creating a new series of packs (see Superpack 1) - which would become the Obsession packseries, starting in october. All this was also reported in R.A.W 1 (november 1991).

R.A.W 2 (february 1992) reported that The Pride moved on from the group to join Sanity, and that a Finnish section had been opened by Phazer, Extabulator, Hoover, Mac, Top Azz and Voyager.

January 1993 saw the release of Axel's musicdisk Musicland, featuring among other songs his 8th-placed Technology from The Party 1992 the month before.
