It seems like every new communication channel follows the same basic pattern (phone, email, SMS, push notifications, ...). It starts with friend-to-friend communication, but quickly commercial entities realize there's an opportunity to connect with customers. They usually start with something small and helpful, but before long you're overrun with spam. I'm counting the days until my flashlight app tells me I've won a free cruise.
