We already know Facebook is losing among Generation Z, the generation after millennials that prefers Snapchat and Instagram.

Marketing and retail experts pinpointed six other sectors and businesses that are likely to struggle once these teens come of age.

"Generally, members of Generation Z are tech-savvy, pragmatic, open-minded, individualistic — but also socially responsible," An Hodgson, an income and expenditure manager at Euromonitor International, told Business Insider.

Ishan Goel, a 19-year-old marketing strategist with the Mark Cuban Companies, said it was "not cool" for his fellow Gen Zers to be on Facebook. For today's teens, Facebook is just a tool for group chats or keeping up with parents.

"People aren't wanting to post stuff consistently," Goel told Business Insider.

People in Generation Z were born between roughly 1995 and 2010. This cohort of current teens is on track to kill Facebook, Business Insider's Mark Abadi reported earlier this year.

Only 9% of teens say Facebook is their preferred social-media platform, a survey from Piper Jaffray found last year. Gen Z prefers Snapchat and Instagram, while older millennials are the biggest chunk of Facebook's users.

"Generally, members of Generation Z are tech-savvy, pragmatic, open-minded, individualistic — but also socially responsible," An Hodgson, an income and expenditure manager at Euromonitor International, told Business Insider.

Hodgson added: "Because Gen Zers are individualistic and value their privacy, they prefer anonymous social media like Snapchat, Secret, and Whisper rather than Facebook."

Millennials are said to have already killed bar soap, diamonds, and napkins. Here's what's on Gen Z's hit list.
