Copyright is a legal tool that protects creative works. Think of it like a deed to a house, but for something you've made, like a song, a book, or a photograph. As soon as you create something original and fix it in a tangible form—like writing it down or recording it—you automatically have a copyright for it. You don’t have to file any paperwork.

The main purpose of copyright is to encourage creativity. By giving creators exclusive rights over their work for a limited time, the law allows them to benefit from their efforts. This encourages them to create and share new things, which ultimately enriches public culture.

Copyright law applies to a wide range of original works. This includes things like:

• Literary works: Books, poems, articles, and computer code.
• Musical works: Compositions and lyrics.
• Dramatic works: Plays and screenplays.
• Artistic works: Paintings, sculptures, photographs, and graphics.
• Audiovisual works: Movies, TV shows, and online videos.
• Architectural works: Building designs.

An important distinction to make is that copyright protects the expression of an idea, not the idea itself. You can't copyright the idea of a wizard school, but you can copyright a specific book about a particular boy wizard at a particular school.

Owning a copyright gives you a bundle of exclusive rights. This means that, as the copyright holder, you are the only one who can legally do the following things with your work:

• Reproduce it: Make copies of the work.
• Create derivative works: Make new works based on the original, like a movie based on a book.
• Distribute it: Sell or give copies to the public.
• Perform it publicly: For plays, music, or movies.
• Display it publicly: For visual art like paintings or photos.

If someone else wants to do any of these things, they need to get your permission first. These rights give you control over how your work is used and shared.

Copyright protection doesn't last forever. The duration has changed over the years, but a general rule for works created today is the life of the author plus an additional 70 years. This ensures that the creator and their immediate heirs can benefit from the work.

For works created by a company (a "work made for hire") or for anonymous works, the term is different. In these cases, copyright typically lasts for 95 years from the date of publication or 120 years from the date of creation, whichever is shorter.

Once the copyright term expires, the work enters the public domain. This means it is no longer protected by copyright and is free for anyone to use, share, and build upon without permission.
