Founded in 1999 and first profitable in 2016, Chris Barton and Philip Inghelbrecht’s app Shazam was acquired by Apple in 2018 for $400 million. Shazam is an app that uses the built in microphones on a smartphone to record a sample of a song played near the device and compares the sample to a library of song “fingerprints” to find a match. This process allows the app to identify what song is playing in a user’s environment. The simple idea was quite difficult to execute as a method of cataloging song “fingerprints” had to be established before it was possible to compare the environment sample and find a match. Once this was finally overcome through clever methodology and coding (and a patent lawsuit with Tune Hunter in 2009), the company was acquired by Apple Inc. and the software was incorporated into iOS in addition to the existing mobile apps available across multiple platforms.
