Ben & Jerry's partnered with Buzzfeed to promote the ice cream brand’s vegan line from World Vegan Day on November 1 until November 7, 2018. Throughout that time period, the site promoted the brand’s nondairy flavors in honor of World Vegan Day. The partnership was the first time BuzzFeed offered a week-long sponsored content package—where advertisements and editorial content supported Ben & Jerry’s vegan line across its platforms. The collaboration was an effort to relate to the two brands' overlapping consumer base, which BuzzFeed reveals were both highly receptive to vegan-related content.
