The NFL has always been vigilant about use of its logos, broadcasts, and more; it's just that as infringement becomes easier and more prevalent (generally due to technological advances), such vigilance becomes more apparent to the general public.
A corporate entity would not have a copyright date.
Using NFL or team logos requires a license; this is an issue of trademark, rather than copyright.
There are no "copyright folks" at the NFL. What you need is the licensing department and all the contact information is at the related link below (you'll need a pdf reader.)
AnswerNo. All NFL logos are protected by, in some cases, both trademark and copyright law.
The National Football League, the professional American football league consisting of 32 teams, maintains a very strict copyright declaration. Although copyright exists already, even without the notice, this declaration is intended to protect NFL broadcasts from being reused in any fashion. The notice follows a standard wording, such as: "This telecast is copyrighted by the NFL for the private use of our audience. Any other use of this telecast or any pictures, descriptions, or accounts of the game without the NFL's consent is prohibited." So, no, you cannot make a Podcast that shows ANY part of a football game! The NFL can not only make you delete it from the Internet but they could also sue you. Courts can fine you.
Yes, showing NFL games in public without the proper authorization from the NFL or its authorized broadcasters would likely violate copyright law. Publicly displaying copyrighted content, such as live sports broadcasts, usually requires a license or permission from the copyright holder.
No, and copyright would be less of a problem than trademark. The NFL is particularly fastidious about protecting its brands.
The National Football League has a strict numbering policy, so quarterbacks can only wear numbers between 1 and 19. Among current NFL starters, the highest number worn by a quarterback is Peyton Manning's No. 18.
Yes, as long as the new "artwork" is not "derivative" of the original art and you do not misrepresent it as produced or licensed by the copyright owner. See related question on NFL materials: "Can you legally make an item using NFL fabric and sell it?"
This question makes no sense. Please rephrase it.
It would be prudent to ask for permission.
If they are copies you taped of the tv, yes it is a violation. If you purchase a game tape from an authorized NFL retailer, you can re-sell it, but cannot keep or make a copy. You can buy your original copy but not make several copies and sell all of them.
