A different domain (ex. .TV, .us., .gov, etc.) doesn’t always mean it’s the same site. I couldn’t find any notable cases (or court cases) but an example could be mylocalbusiness.de versuses mylocalbusiness.pt
In that situation I can create a website for my local business in Germany and not have to worry about an identically named business in Portugal potentially.
It is important to keep this in mind though because spoofing one website for malicious purposes is a real hazard.
