Amazon's Dash Button was a $5 button for detergent — obsolete in 3 years

Amazon launched the Dash Button in 2015: a small, $5 WiFi-connected button branded with a specific product (Tide, Bounty, Duracell) that you stuck on your washing machine or pantry wall. Press it, and Amazon orders more. The concept was 'frictionless reordering' — remove the app, the search, the cart.

But the Dash Button was a hardware solution to a software problem. Amazon's own app, Alexa voice ordering, and Subscribe & Save all did the same thing without a physical button on your wall. The Dash Button added a step (walk to the button, press it) that the smartphone had already eliminated.

Amazon stopped selling physical Dash Buttons in February 2019, replacing them with 'virtual' Dash Buttons in the app. The case illustrated how a single-purpose hardware device is vulnerable to obsolescence when the general-purpose device in your pocket already does the job. The best button is the one you don't need.

Amazon killed the Dash Button in 2019 because the smartphone already did the job free; the $5 button added a step the phone had eliminated.

A single-purpose hardware device is vulnerable to the general-purpose device in your pocket. When the phone already does it, the dedicated button is a novelty.

Amazon replaced physical Dash Buttons with virtual ones and 'Dash Replenishment' integrated into smart appliances. The concept of frictionless reordering survived; the button did not. The case is cited as an example of how platform owners can obsolete their own hardware.
