Doom sold its full version by mail order in 1993

The workload

id Software's own company history page states that on 10 December 1993 it 'released its much-anticipated DOOM, the first shareware game to be distributed under the id label.' The same page describes the mechanics in the company's own words: id would 'freely release a portion of the game to the public through online services and the Internet. Then, if the customer likes the game, the full version can be ordered directly from id,' by mail, over an '1-800-id-games' order line, rather than through a retail shelf. Running this model required id to maintain its own order-fulfilment line and its own file distribution alongside a separate retail partner for boxed copies, work a modern subscription vendor now hands to a payment processor.

What the documents show

The company's own history page, archived in 1998, states that 'an estimated 15 million shareware copies' of Doom were downloaded worldwide and that 'more than 250,000 people' registered the full product, both self-reported company figures, with 'estimated' the company's own hedge on the first number and neither tied to an independent audit. A separate id Software file-archive page from the same period, listing shareware and 'registered' versions for download, corroborates that the split was a real, functioning distribution mechanism rather than only a marketing description. The company's current site, retrieved 16 September 2026, still refers in passing to 'the shareware days,' confirming its own continuity claim back to a 1991 founding, though it gives no operational detail about 1993 specifically.

The operating cost

None of id's own pages states a dollar cost for running the order line or the shareware channel itself. The 1998 history page names outcomes, registrations, downloads, but not id's cost per registration, and it does not state Doom's registered price as a specific figure at all. Establishing that cost would require a separate document, such as a period order form, that these two id-published pages do not include.

The stop condition

id's own account frames the shareware release as a standing distribution channel rather than a time-limited offer: the history page describes the free episode as available indefinitely alongside the registered version, not as a promotion with an end date. No source here states when, if ever, id considered ending shareware distribution for Doom specifically; the company continued using the same 'try before you buy' language for its next release, Quake, in 1996, per the same history page. Any specific stop condition for a single title's shareware run is not documented and would be an editorial estimate.

• Does a company-reported download estimate, hedged with the word 'estimated,' carry the same weight as a registration count taken from an order line?
• What would it take to convert a free, portion-of-the-product release into paid registrations at a rate a modern subscription funnel would recognize?
• Is a toll-free order line a fixed or variable cost, and how would that change the shareware math?

Doom's 1993 release is well documented by id Software's own account of it, but that account is a company's retrospective self-description, written a few years after the fact, not a contemporaneous financial record.
