Adding to the response given by Venkat, I would like to mention it is DMCA (not DCMA), which stands for Digital Millennium Copyright Act. This act takes care of the penalties upon any kind of copyright infringement on the Internet or World Wide Web.
Generally, as soon as a website or blog publishes its original content of any form (be it text, photo, audio, video, document or scripts), it becomes the property of that website and/or the original author.
Copyright terms and conditions control the scope of the usability of the copyrighted content. In other words, copyright refers to the ownership of any intellectual property that exists due to your efforts and intellect.
While as soon as you write a book, a blog or something on your website, it becomes your property and becomes copyrighted, 'but' at the same time, if someone challenges your work and proves in the court that it belongs to him/her, you should also have enough proof of creating and ownership of the content, hence it is always good to have a copyright for your work in your country (This is a paid copyright option and comes at varied monetary charges for different types of intellectual properties including music and drama as well).
For Indian owners of some content, they can contact the Copyright Office of India, located at New Delhi, India. All the latest information regarding the 'Copyright Act of India' and the ownership of intellectual property in India can be known from their website and office.
One can use the official telephone number of Copyright Office in India that is, +91-11-23362436 or mail them at copyright[at]nic.in
