Thanksgiving. What better opportunity to observe the marketing and communicating across generations? Let’s look around the table. Traditional, it is not — at least not in a Norman Rockwell kind of way. Boomer grandparents are on their smartphones or iPads, catching up on Facebook and posting pictures of the family gathered around the table. Their Gen X children are snapping digital photos of the braised Brussels sprouts with bacon and tart cranberries to impress their friends on Facebook, while perusing pre-Black Friday sales online. Their Millennial children are Instagramming the same Brussels sprouts, but with an artsy twist and the hashtag #foodporn. Their Generation Z teenage siblings are sending Snapchat photos, streaming YouTube videos, checking WhatsApp to see when their latest crush was last online, and basically moving between social sites faster than the crescent rolls are disappearing. Any one of those people could be taking selfies (with relatives or Brussels sprouts).
