Legal issues with nba player names, profiles, logos? I am searching for this topic and I found a similar question asked check here Legal issues around using real players names and team emblems in an open source game however I have specific questions where I don't know where to ask. So I'll make an nba quiz mini game and I need to know if there might cause some trouble using player profile images, names, team names and logos. I found about a dozen suck mobile apps which use real names also some use photos as well. In case I need a permission or check the customs, where to contact? where can I find such regulations? Lets say I am allowed to use profile images, can I use the official images found on nba.com or yahoo or any sports website? If not, where to get all player photos? sure can't capture them one by one ) As for team logos, there are logo quiz apps which mentions hundreds of logos of different international famous companies, I don't think the app owner contacted each company. Any related information would help. Thanks
