I am thinking of creating a sports blog, and would like to know if you need permission from a team or the league to write this blog. For example if I am writing a article about the Philadelphia Phillies would I need to obtain permission from the team to write that article? It is worth noting that I would be using AdSense to generate revenue from views of the blog, but not charging people money to view the blog.
I don't know if this matters but I live in PA.
I am going to be writing about different stats and statistics for different sports teams, but I'm not sure if I can use the team names or player's names without infringing on copyright.
