17 brands millennials loved that 'kids these days' are avoiding

The trend among Gen Z: Among the 160-plus brands that youth-insights firm Ypulse monitors, Crocs do especially poorly for brand influence among Gen Z consumers, Calise told Business Insider. The garden shoe peaked in 2007 across all age groups.

The trend among Gen Z: Snapchat and Instagram are becoming the preferred social networks for teens. Only 8% of teens said Facebook is their favorite social media platform in 2018, while 45% chose Snapchat and 26% picked Instagram.

The trend among Gen Z: Steven Madden, known for its teetering heels and platform sandals, dominated as a top pick for teen girls for years, reaching No. 2 most-preferred among upper-income teens in 2007. Now, as the women's shoe industry slants from heels to sneakers, sporty options like Nike and adidas are the leading footwear options for teens.

The trend among Gen Z: Only 8% of teens told YPulse that Dell is a "popular" brand, compared to Apple at 61%. Calise told Business Insider that Dell has lost as a technology company among this teen cohort because it excels at desktop and laptop computers — but teens mostly use their smartphones to navigate the world.

The trend among Gen Z: Preppy looks were big in the late 1990s and 2000s, when millennials were teens, but now Piper Jaffray said Gen Z teens are preferring streetwear styles led by brands like Supreme.

The trend among Gen Z: Puma was a top 5 teen choice for footwear in the late 2000s. But, even though Gen Zs love sneakers and streetwear brands, Puma has lost out in 2018 to brands like Vans and Adidas. (Its celebrity-studded marketing push, with ambassadors like Rihanna and Kylie Jenner, might just help a comeback, though.)

The trend among Gen Z: Ugg boots, the love-to-hate footwear of the 2000s, are no longer on teens' radars, though they were a top-five choice from 2008 to 2013. Gen Zs have their own ugly shoe trend: the chunky white dad sneaker.

The trend among Gen Z: Hollister was the top brand among upper-income teens for much of the 2000s. Nike is the top pick for Gen Zs in 2018, followed by American Eagle and Adidas. It shows that Gen Zs prefer athleisure trends over Hollister's ubiquitous branded t-shirts, polos, and jeans.

The trend among Gen Z: Almost 10% of millennials say they pay for Pandora, compared with just 6% of Gen Zers, a study by the consulting firm Fluent found. Generation Z, more than any other generation, prefers subscribing to Apple Music, Spotify, and YouTube Red.

The trend among Gen Z: The oldest Gen Zs and oldest millennials adored this preppy shoe in the early 2010s, but sneakers are now the go-to comfy shoe.

The trend among Gen Z: Gen Zs tend to be pragmatic and frugal. That quality has been pushing them away from Tiffany & Co, which teens see as too "glitzy," Business Insider previously reported. Meanwhile, the 180-year-old retailer has been making inroads in ecommerce and targeting "millennials" — but not "Gen Zs."

The trend among Gen Z: When they were teenagers, millennials were a leading demographic group for Vera Bradley, that purveyor of quilted cotton handbags and backpacks. But today's teens named Michael Kors and Gucci as their favorite handbag makers.

The trend among Gen Z: While Skechers have an awareness level of more than 90% among teens, fewer than 20% actually find the brand cool, according to YPulse. Skechers is "caught in a fashion 'no man's land,' where they're offering teens neither classic nor fresh styles," Calise told Business Insider.

The trend among Gen Z: Calise said Gap was one of the leading retailers of the 90s and 2000s for teen millennials, but now it's losing out. While 39% of teens told YPulse they would consider buying from Gap in the future, young consumer-focused stores like American Eagle and fast fashion retailers like Forever 21 are leading in the Gen Z sector.

The trend among Gen Z: While Abercrombie sales have upticked in 2018, for the first time in five years, the once-ubiquitous teen retailer is not what it used to be in the 1990s and 2000s. While much of that is owned to teens' move from preppy styles to streetwear looks, Abercrombie's corporate leadership might also turn off Gen Z, who tend to shop at places that are socially responsible.

The trend among Gen Z: A fifth of Gen Z consumers told YPulse that they plan on buying Red Bull, compared to 69% with plans to buy Gatorade. Calise attributed that to teens' interest in healthier food as a whole, and a beverage space that's increasingly crowded with kombucha, coconut water, and cold brew.
