I've mainly heard this greeting within the Gujarati community (but perhaps it's usage is more universal). I don't know if this is a new trend or some sort of religious zeal (i.e., to ), but I agree with Illuminatus that it's mainly used by Krishna bhakts. You say you see this in the saas-bahu serials. Those shows, as I'm sure you're aware, do an excellent job of depicting artificial life, so perhaps they're trying to promulgate some upper class/religious righteousness to counterbalance all the sister in-law backstabbing, disgruntled mother in-law invective, greedy newly discovered fraternal treachery, and love trysts that make them infamous.
