With the rise in popularity of breakbeat music and the advent of digital audio samplers, enterprising companies started selling "breakbeat packages" for the express purpose of helping artists create breakbeats. A breakbeat kit CD would contain many breakbeat samples from different songs and artists, often without the artist's permission or even knowledge. One example of this is the Amen Break, from a song by The Winstons, who hold the copyright. However, a company named Zero-G Limited released a "jungle construction kit" containing hundreds of audio samples. One appeared to be an exact copy of the Amen break. It was slightly sped up. Zero-G Limited claimed copyright since a copyright symbol was included on the product's packaging. However, when it came to Zero-G Limited's notice that there may be another claim on the copyright of the audio sample in question, they removed it from the product. The Winstons have not received royalties for third-party use of samples of the break recorded on their original music release.
