Airfoil has been in development since 2005, with versions available all the way back to Mac OS X 10.2 (!). Below, you can see screenshots of Airfoil through the years.

When Apple released the AirPort Express device, it could only receive audio from iTunes. The ability to send non-iTunes audio was much sought-after, and because of our ability to capture any audio (with Audio Hijack) and broadcast any audio (with Nicecast), many users requested that we make it possible. With the release of Airfoil 1.0 in 2005, we did.
Airfoil 2.0 shipped just before the Macworld Expo in San Francisco in January 2006. This free update brought the incredible ability to send to multiple AirPort Express units at the same time. It was a world first. Alas, mere days later, at Macworld, Apple announced the same functionality had been built into iTunes.
This update also overhauled the interface, with a look that would provide a foundation for the app for many years to come.
The most notable items in Airfoil 3 were two companion applications: Airfoil Speakers and Airfoil Video Player. The former allowed other Macs to become receivers for Airfoil, while the latter made it possible to watch local video in sync with remote streamed audio, by delaying the video to overcome the latency of streaming.
Many changes were made in Airfoil 3.5. Most visible are the ability to remotely control Airfoil from remote speakers, as well as a control for where local audio should play when captured by Airfoil.
Airfoil 4 saw most of the app’s visuals overhauled. This was also one of our first apps to feature a welcome window, which sought to introduce the app to new users. Finally, Airfoil Video Player was greatly expanded, to play web video as well as DVDs, in addition to local files.
Airfoil 5 saw another major interface redesign. Gone were the dark colors, replaced by blues. Coincidentally, this update also added the ability to send to Bluetooth devices, in addition to AirPlay hardware.
Airfoil 5.5 came hot on the heels of version 5, adding the ability to send to Chromecast devices. Airfoil Satellite’s Preferences window was also revamped, and Airfoil stopped sorting speakers into distinct sections based on type.
