Royalty streams refer to the income generated from the rights to use creative works, such as music, books, or patents. When an artist, author, or inventor creates something, they can earn money each time their work is used or sold. This income can come from various sources, including licensing agreements, performance royalties, and sales royalties. These streams provide a way for creators to receive ongoing compensation for their work, even after the initial sale. For example, a musician may earn royalties every time their song is played on the radio or streamed online. This system encourages creativity and supports artists financially over time.
