Millennials make up a crucial group of consumers.
Ad agency Moosylvania asked over 3,500 millennials — defined as 20 to 35-year-olds — to select their favorite brands over the past three years.
Great Questions, LLC helped rank the winning brands.
These brands are the ones that came out on top.
Some are surprising — others, not so much.
A common theme for successful brands? Engaging with millennial consumers via social media.
100. Audi
Robert Libetti/ Business Insider Headquarters: Ingolstadt, Germany
Place on last poll: Not applicable (*Note: Moosylvania's previous poll from spring 2015 only contained the top 50 brands for millennials.)
Why it's hot: Audi used a mobile app to connect with its users during the 2015 Audi Cup, allowing users to be parts of the experience.
95. Carter's
Headquarters: Atlanta, Georgia
Place on last poll: N/A
Why it's hot: The Carter's website proves that the brand has nailed ecommerce. In fact, the brand has mastered social media. Therefore, Moosylvania found that it's very appealing to millennial parents who want to share photos of their babies (wearing Carter's apparel, no less) with its hashtag #lovecarters. Carter's features those photos of adorable tykes on its website, too.
90. Anthropologie
Headquarters: Philadelphia, Pennsylvania
Place on last poll: N/A
Why it's hot: Anthropologie is Urban Outfitter's finely curated and refined sister brand, so it makes sense that the brand chose to engage with its consumers via Pinterest, the social channel that's all about curation, with its #PintoWin contest.
82. Gucci

Headquarters: Florence, Italy
Place on last poll: N/A
Why it's hot: Gucci engaged with millennial consumers with a campaign surrounding its classic loafer. The campaign included quizzes, a Pinterest board, and a #Gucci1953HorsebitLoafter hashtag, cementing the luxury brand as a participant in the social community with its own voice.
73. Sephora

Headquarters: Paris, France
Place on last poll: N/A
Why it's hot: Sephora is the premiere destination for all things beauty. Its points and rewards system encourages brand loyalty; consumers keep coming back to obtain points to earn new products. Sephora's app, Beauty Insider, features "Beauty Boards," which allow shoppers to show off their best new looks. It also serves an inspiration board, in the same vein as Pinterest.
67. Marvel
Headquarters: New York, NY
Place on last poll: N/A
Why it's hot: Marvel is obviously a huge power force in pop culture — its "Avengers" movies (amongst others) are smash hits, grossing billions of dollars worldwide. Marvel knows its movies generate tremendous hype, so it kept its "Avengers: Age of Ultron" trailer 'locked' until fans tweeted enough. Moosylvania notes that Marvel received an outrageous amount of tweets — an average of 8,100 tweets a minute worldwide — so it was obviously a successful campaign.
58. Kraft

Headquarters: Northfield, Illinois
Place on last poll: 40
Why it's hot: Kraft scored big points with millennials this year when it announced that starting in 2016, its original Macaroni & Cheese will get its color from natural spices like paprika instead of from artificial additives Yellow 5 and Yellow 6. Kraft's latest ads have also appealed to millennials, Moosylvania explains, since they look more like GIFs — something millennials love.
52. Asus

Headquarters: Taipei, Taiwan
Place on last poll: 50
Why it's hot: This Taiwanese company is a huge PC vendor. The brand is making headlines for its inexpensive Android smartphone and ZenWatch. The brand also plays on popular memes (for example, birds with arms), and has optimized its Internet friendly content, including games and videos. But as more consumers turn to Android, Asus could be challenged.
49. Dove
Headquarters: Rotterdam, Netherlands
Place last year: 26
Why it's hot: Dove, which is owned by Unilever, has been succeeding with its "real beauty" campaigns, which emphasizes natural looks over the typically airbrushed ads, resonate well with millennials. The brand's "Self Esteem" Snapchat campaign, in which girls could Snapchat their insecurities and receive a positive response, highlighted the brand's ethos.
47. Hershey's
Headquarters: Hershey, Pennsylvania
Plac last poll: 37
Why it's hot: Hershey's has dropped artificial colorings from its chocolate. "We are committed to making our products using ingredients that are simple and easy-to-understand, like fresh milk from local farms, roasted California almonds, cocoa beans and sugar – ingredients you recognize, know and trust," the company said in a news release.
46. BMW
Headquarters: Munich, Germany
Place on last poll: N/A
Why it's hot: BMW served as an official sponsor of the United States Olympics team in 2014, and the automobile company sponsored social campaigns with incentives for consumers, like its #BMWborntoslide campaign, wherein consumers who photographed themselves sliding could a win a trip to Utah to ride in a real bobsled.
42. Honda
Headquarters: Hamamatsu, Japan
Place on last poll: 31
Why it's hot: Honda's fuel-efficient, compact cars appeal to millennials. But most importantly, the company's YouTube campaigns for Honda Fit excited millennials. Honda has partnered with major companies such as iHeartRadio, Live Nation, and REVOLT for its YouTube channel.
39. Macy's

Headquarters: Cincinnati, Ohio
Place on last poll: 16
Why it's hot: Millennials are spending less money on clothes, which is bad news for Macy's. In order to attract younger shoppers, the brand has been investing in trendier clothing lines and other categories like home goods and cosmetics. But Macy's has been also focusing on its social campaign, like its #MacysLoveMoms. For every photo memory or tweet shared, the company donated $3 to a charity.
38. Express
Headquarters: Columbus, Ohio
Place on last poll: N/A
Why it's hot: Express rewards shoppers by not just using their store credit cards, but by getting involved with Express in other ways, too — like retweeting its tweets and singing up for its text message alerts. For every 2,500 points, shoppers earn $10. This helps Express ensure customer loyalty.
33. Toyota
Headquarters: Toyota, Aichi Prefecture, Japan
Place on last poll: N/A
Why it's hot: Toyota has teamed up with YouTube stars like Rhett & Link for campaigns, proving it knows how to cater to its audiences. Moosylvania also highlights its 2014 #CarsThatFeel campaign, which incorporated LED lights into Priuses for the 2014 Vivid Light Festival in Sydney Harbor. The cars had 'personalities' and 'feelings' and interacted with people, which is certainly intriguing.
7. Amazon
Headquarters: Seattle, Washington
Place on last poll: 11
Why it's hot: This year, the company started offering one-hour delivery for members of its Prime service and expanded its grocery delivery business to New York City. The company also announced a new gadget called the Dash Button, which will make it easier for consumers to order household items, such as detergent, when they are running low. Amazon has also connected with Twitter.
4. Sony

Place last poll: 4
Why it's hot: Sony's Playstation, gaming, photo, and music businesses are booming. Sony is aggressively investing in these areas. The company also has popular smartphones. Sony also utilized a concept called One Stadium Live for the 2014 World Cup, creating a single platform for all World Cup-related social media.
