Assuming the site that's doing this started doing it recently, I think this is a case of copying Facebook.
On Facebook, companies, interests ect have "Pages", this is in part because products and services used to act just like normal people, they were 'friends' and they had access to all the info your friends did. Huge privacy violation, and many companies used this to their advantage (you could "friend" a potential employee and suddenly see all their facebook posts).
On Facebook the "Fan Page" makes a human clearly distinct from a product, service, interest or even celebrity's page. Arguably the difference is people have a Profile describing them, which is usually put together of canonical personal information.
Companies have a Page constructed by them, usually by a marketing team. They serve a similar function but the profile is assumed to be literally true and not "marketing". A company is assumed to have put together information supporting their business, not simply a description of what they are.
