Many creators and inventors use the copyright symbol even if it’s not needed. Rather than needing to display the copyright symbol and the identification information, it granted rights automatically. In 1989, however, the Copyright Act removed the need to post copyright notice.

The copyright symbol was developed in accordance with the 1952 Universal Copyright Convention which said the copyright symbol must appear, along with the name of the copyright owner and the year the work was produced. A sound recording may have a P inside a circle - ℗ - but it will have a nearly identical meaning and purpose. You’ll see a C inside a circle, which typically looks like © in print. A copyright symbol is used to show that someone owns the legal rights to make, use, and distribute particular works.
