Genuine question, how did 'Swami Samarth' gained god status in almost every household?

This is not a hate post or criticism to anyone's beliefs. And I dont want to offend anyone. But I am genuinely curious. How did it happen? Coz 10-15 yrs back lot of people worshiped them but still main gods and deities in 'Devhara' were Lord Mahadev, Shriram, Hanuman, Kuldaivat etc. Swami samarth were more like saint but not god. Like visit temple occasionally, do some special celebrations on Jayanti but they were rarely part of daily prayers. But nowadays they have gained actual status of god. What are your thoughts?
