I am a mid-aged typical American, Bob Johnson. You probably know me from social media. For the better part of a half-century, as the active personality of social platforms, I’ve been guiding and inspiring people to upgrade their homes with modern technologies, especially in the realm of the projector industry. I have learned firsthand about it from my father, especially about projectors, and I’ve written more than a dozen articles about them. You can say guiding people about projectors is my life’s work.
