Platform envelopment

Platform envelopment is a strategy in which one platform provider enters another platform’s market by combining its own functionality with that of the target, creating a bundled multi-platform offering.^[1] Markets that evolve rapidly are especially rich in envelopment opportunities, and firms in these industries face a continuous risk of being displaced or rendered obsolete.

An example is the convergence of mobile phones and portable media players, which were once separate markets but gradually merged into multifunctional devices. When a stand-alone business faces an envelopment attack, its strategic options are often limited to adapting its business model or selling to the attacker.

One well-documented case involves RealPlayer, which had established a two-sided market in the streaming video sector. RealNetworks subsidized consumers while charging content providers for its streaming software. Microsoft launched an envelopment attack by integrating streaming server software with its Windows NT operating system. This bundling strategy reduced the incentive for content providers to continue paying Real, as Microsoft’s platform was already embedded in Windows and tied to the widely distributed Windows Media Player.^[2]
