At first glance, this appears to be a vintage ad by the "Soda Pop Board of America" extolling the virtues of drinking cola at an early age. It's been circulating around the internet for quite a while, during which time many sites have angrily responded to the claims made in the ad.
For instance, the Queen Anne Chiropractic Center
declared that the ad demonstrates "just how wicked the Mad Men of yesteryear were." The parenting blog babble.com
wrote: "We all know that, on occasion, advertisements can offer some fairly crappy advice. Back in the day, though, ads had no shame." And NaturalNews.com
offered the ad as evidence that, "Soda companies, much like drug companies, have relentlessly tried to convince parents that forcing their products onto their children is a smart thing to do."
I could go on, but I'll cut to the chase: the ad isn't real. It's just a very successful vintage-ad parody created in 2002 by RJ White, who explains its full provenance on his blog Ice Cream Motor
About seven or eight years ago, I made this fake ad, exhorting parents to give soda to their babies. It was done on a bored afternoon when J.D. Ryznar asked for someone to make that very specific thing on his livejournal. I whipped it together, posted it to the web, joke over.
THEN. A couple of years later- it started showing up online, in those weird lists that pop up every so often with a "Oh man, ads sure were strange back then, weren't they?" theme. Thing is, those ads are largely real and mine is not and very obviously so.
White links to the original livejournal post
that inspired him to create the ad. His ad seems to be currently enjoying a fresh wave of popularity thanks to tumblr and pinterest which are presenting it to new audiences, many of whom (once again) seem to be accepting it at face value as a genuine vintage ad.
