ChurchRelevance.com has a great article and video link from the The Church Law Group outlining some great guidelines on enjoying a Super Bowl watch party at your church while respecting copyright law.
For those of you who've ever made an attempt at trying to understand copyright law, you will find these guidelines very reasonable and fair.
Enjoy the game!
P.S. The video also includes a great, understandable overview of what copyright and fair use are and what they affect, particularly relating to church use.
