Paying guest (or PG in short) concept started little more than a century back. [Book, "The Paying Guests" by Sarah Waters, published in 1922]. 

Accommodations in most cities are very costly.  For one person, renting a full apartment and spending on rent, utilities, furniture, etc. is too expensive for most people.  PG facility is the best!
