Ever notice when you get something in your head you start seeing that thing everywhere? I remember when I was a teenager I wanted a cordless telephone. I begged my parents for one with the claim that "everyone had one." It did seem like they did: Carrie, my short, rebellous friend would walk around her house on one for hours, Monica down the street had one she'd hide from her brother, Radio Shack had them prominently on display. It felt like I was the only person without one and I had the 1980s version of FOMO.
