Justine Ezarik and Joey Graceffa are no strangers to technology.

Both Ezarik, who’s known to fans as iJustine, and Graceffa post videos almost daily to their YouTube channels. Come January, the two digital media personalities will serve as Entertainment Matters ambassadors for CES 2016.

Presented by Variety, Entertainment Matters is a CES program developed to help the Hollywood community navigate the technology show.

Having attended CES in the past, Ezarik recommends attendees map out a floor plan before tackling the conference and wear comfortable shoes. how will be Graceffa’s first time at the technology conference. “I’ve actually seen a lot through Justine’s vlogs in the past, but I’m excited to experience it in person,” Graceffa said.

While vlogging is a full-time job for Ezarik and Graceffa, they both agree it doesn’t feel like a tradition full-time job. “Having a successful YouTube account doesn’t really affect my personal relationships because most of my friends are YouTubers. However, that is kind of like a weird thing because we’re almost like coworkers that are friends,” Graceffa said.

Looking forward, both stars have exciting video in the works. Ezarik is working on a virtual-reality 360-degree video. ” It kind of tells my story of when I first came to LA and what made me want to move here,” Ezarik said. “It starts from the first place I ever went and it follows me back to that place 10 years later.”
