The most common format is: **© Year Owner Name** For example: **© 2026 Your Name** If you continue updating a work over multiple years, you can also write: **© 2024–2026 Your Name** The owner's name can be your personal name, brand name, or company name. *2) About Copyright Protection In many countries, including those that follow the Berne Convention, copyright is created automatically when an original work is made. You do not need to add a copyright notice for your work to be protected. However, adding a copyright notice such as **© Year Owner Name** makes it clear who owns the work and can help discourage unauthorized use. If someone intentionally removes a copyright notice or watermark before using your work without permission, it may be considered evidence that they knew the work was protected. A copyright notice is not required for copyright protection, but it is a widely used way to show ownership and help protect your work.
