accountFacebook's business model was novel at market entry because it offered a more efficient form of information exchange, and it utilized indirect network effects by attracting users who acted as both producers and consumers of content, which discouraged migration to other providers.

referenceCurrent business model theory identifies five primary methods to establish lock-in: loyalty, sunk costs, direct network effects, indirect network effects, and data network effects.

claimMechanisms that contribute to the activation of a lock-in business model theme include sunk costs (Schmalensee, 1992), loyalty (Malhotra & Kubowicz Malhotra, 2013), direct network effects, indirect network effects (Clements, 2004), and data network effects emerging from machine learning technologies (Gregory et al., 2021; Climent et al., 2024; Haftor et al., 2024).

claimAmazon, its suppliers, and its customers create a lock-in effect through mutual investments that lead to sunk costs and indirect network effects, making it costly and risky for competitors like Walmart Plus to entice these actors to migrate.

claimNespresso's coffee business ecosystem benefits from indirect network effects generated by the availability of multiple compatible machines, which increases the value and appeal of purchasing Nespresso coffee capsules.

claimBusiness model theory identifies six mechanisms for activating lock-in: brand loyalty, sunk costs, direct network effects, indirect network effects, data network effects, and the business ecosystem.
