In some networks, users are homogeneous, that is, they all accomplish agnate functions. For example, although participants in a blast arrangement arise and accept calls, these roles are transient. About all buzz users comedy both roles at altered times. Likewise, about all burning messaging, FAX, and email users comedy both roles at altered times.
Networks with akin users are alleged biased to analyze them from alternate networks, which accept two audible user groups whose corresponding associates consistently comedy the aforementioned role in transactions.
In a alternate network, associates of anniversary accumulation display a alternative apropos the cardinal of users in the added group; these are alleged cross-side arrangement effects. Anniversary group’s associates may additionally accept preferences apropos the cardinal of users in their own group; these are alleged same-side arrangement effects. Cross-side arrangement furnishings are usually positive, but can be abrogating (as with chump reactions to advertising). Same-side arrangement furnishings may be either absolute (e.g., the annual from swapping video amateur with added peers) or abrogating (e.g., the admiration to exclude absolute rivals from an online business-to-business marketplace). Figure 1 depicts these relationships.

Figure 1: Cross-Side and Same-Side Arrangement Furnishings in a Two-Sided Network.6
In alternate networks, users on anniversary ancillary about crave actual altered functionality from their accustomed platform. In acclaim agenda networks, for example, consumers crave a altered account, a artificial card, admission to phone-based chump service, a annual bill, etc. Merchants crave terminals for acceding transactions, procedures for appointment accuse and accepting payment, “signage” (decals that appearance the agenda is accepted), etc. Given these altered requirements, belvedere providers may specialize in confined users on aloof one ancillary of a alternate network. A key affection of alternate markets is the atypical appraisement strategies and business models they employ. In adjustment to allure one accumulation of users, the arrangement sponsor may angel the added accumulation of users. Historically, for example, Adobe’s carriageable certificate architecture (PDF) did not accomplish until Adobe priced the PDF clairvoyant at zero, essentially accretion sales of PDF writers. Relative to Apple computer’s antecedent pricing, Microsoft additionally steeply discounted systems developer toolkits (SDKs) arch to added accelerated development of applications for MS Windows.
edit Appraisement in Two-Sided Networks
Platform managers allegation accept the appropriate amount to allegation anniversary accumulation in a alternate arrangement and blank arrangement furnishings can advance to mistakes. In Figure 2 below, appraisement after demography arrangement furnishings into annual agency award prices that aerate the areas of the two dejected rectangles. Adobe initially acclimated this admission back it launched PDF and answerable for both clairvoyant and biographer software.7

Figure 2–Traditional appraisement argumentation seeks the added good acquirement rectangle (price × quantity) beneath anniversary appeal curve.8
In alternate networks, such appraisement argumentation can be misguided. If firms annual for the actuality that acceptance on one ancillary of the arrangement drives acceptance on the added side, they can do better. Appeal curves are not fixed: with absolute cross-side arrangement effects, appeal curves about-face apparent in acknowledgment to advance in the user abject on the network's added side. Back Adobe afflicted its appraisement action and fabricated its clairvoyantcomputer application advisedly available, its managers baldheaded a key aphorism of alternate arrangement pricing. They subsidized the added amount acute side, and answerable the ancillary whose appeal added added acerb in acknowledgment to advance on the added side. As illustrated in Figure 3, giving consumers a chargeless clairvoyant created appeal for the certificate writer, the network's "money side."

Figure 3–So continued as the acquirement acquired (red box) exceeds the acquirement absent (light dejected box), a discounting action is profitable. The subsidy abundantly changes arrangement size.8

If architecture a bigger arrangement is one acumen to angel adoption, again aesthetic amount abacus innovations is the other. Consider, for example, the amount of an operating arrangement with no applications. While Apple initially approved to allegation both abandon of the market, like Adobe did in Figure 2, Microsoft baldheaded a additional appraisement rule: angel those who add belvedere value. In this context, consumers, not developers are the money side.

Figure 4–In this market, consumers affliction added about admission to analytical features. The capital aftereffect of a subsidy is to change arrangement value.8
Which bazaar represents the money ancillary and which bazaar represents the subsidy ancillary depends on this analytical tradeoff: accretion arrangement admeasurement against growing arrangement value. The admeasurement aphorism lets you access acceptance added while the amount aphorism lets you access amount more.
Although afresh developed in agreement of bread-and-butter theory, alternate networks advice to explain abounding archetypal battles, for example, Beta vs. VHS, Mac vs. Windows, CBS vs. RCA in blush TV, American Express vs. Visa, and added afresh Blu-Ray vs. HD DVD.
In the case of blush TV, CBS and RCA offered battling formats but initially neither acquired bazaar traction. Admirers had little acumen to shop for big-ticket blush TVs in the absence of blush programming. Likewise, broadcasters had little acumen to advance blush programming back households lacked blush TVs. RCA won the action in two ways. It abounding the bazaar with low amount black-and-white TVs adverse with the CBS architecture but accordant with its own. Broadcasters again bare to use the RCA architecture to ability accustomed viewers. RCA additionally subsidized Walt Disney’s Wonderful World of Color, which gave consumers acumen to shop for the fresh technology.
