Question

When does someone's work on the Internet become copyrighted?

Answer 1

A copyright comes into existence as soon as the work is fixed in a tangible medium of expression, so copyright exists in a work as soon as the author completes the music composition or play. The author of the work initially owns the copyright. However, ownership of the right may be transferred to others.

In general, registration is voluntary. Copyright exists from the moment the work is created. You will have to register, however, if you wish to bring a lawsuit for infringement of a U.S. work.
