Your original works, on your Wordpress blog, are automatically protected by copyright. Using others' copyright-protected works on your Wordpress blog requires an exemption in the law or permission from the copyright holder.
Using protected materials is legal if you have an exemption in the law or permission from the copyright holder.
Using copyright-free materials is much cheaper and easier than negotiating for a license with the copyright holder of a protected work.
If you are taking a clip from the movie, the movie itself is protected by copyright, but depending on your use, it may be covered by 17USC107. If you are using a photograph of it, the photograph would be protected by copyright, but your use may be covered by 17USC107.
Most uses require permission from the copyright holder, which can be time-consuming and expensive.
Sufficiently original literary works are automatically protected by copyright, even email.
If you are using materials that are not your original work, you need permission from the copyright holder. Works that are entirely your own are automatically protected by copyright as soon as they are fixed in a tangible medium.
If you have received a notice of copyright infringement from Spectrum, it means they believe you have violated copyright laws by using or sharing protected material without permission.
Fashion, for whatever reason, is not protected by copyright, although there is discussion about changing that. In the mean time, you'd be better off registering the label as a trademark, since it's a mark you'd be using in commerce.
You must be licensed to use it. The NASCAR logo is copyright protected and ZEALOUSLY protected by aggressive legal action.
Using protected intellectual property without permission is a violation of federal law.
Straight factual information may not be protected by copyright at all; the expression is protected. Just as when using research from physical sources like books and magazines, summarizing or rewording the material is not infringing, but direct quotes need to be properly cited. (This is less of a copyright issue and more of a plagiarism issue.)If what you want to use from the internet is more creative than factual, you just need an exemption in the law or permission from the rightsholder.
