“I started in the summer of 2006, as an intern for Shade 45,” SiriusXM’s Julia Cunningham explains. “It was such a great time … music blasting in the hallways, special DJ mixes of songs, great people … I loved it.” Thus began the career of one of the satellite radio service’s most infectiously positive and fun personalities. “As a kid, I loved listening to the radio in the back seat of the car. I liked the top-40 stations, along with the oldies stations that my Mom would play,” Cunningham told me.
