In a definite first, TD Ameritrade and Havas have placed an ad in the blockchain as a celebration of innovation and creativity.The ad is made up of 68 Bitcoin transactions, each containing of a string of 80 computer characters that come together to create ASCII art. It can only be viewed visually on a landing page. When it all comes together, the transactions form an image of a flag being held by a hand and featuring the TD Ameritrade logo.The goal was to demystify finance, cryptocurrency and the blockchain. While putting the ad together the team had to consider that since each string is limited to only 80 characters, they had to be clever in character use, and chose only Unicode characters or simple typewriter characters (slashes, equal signs) to create the design. The first transaction contains an initial line, “See the full picture at tdameritrade.com/blockchain.” They then built the rest of the design from 67 additional transactions.Each transaction contains a single line of the ASCII art, which, when taken in totality forms the larger image of a flag.The ad was meant to spread word of mouth in the finance industry and across social media.CreditsClient/Brand: TD AmeritradeCampaign: Greetings from the BlockchainCLIENT:TD AmeritradeDenise Karkos: Chief Marketing OfficerKerin Morrison: Managing Director, Brand & AdvertisingJustin Garcia: Director, Advertising & SocialJim Crews: Senior Manager, Social Media MarketingErin Fairchild: Senior Specialist, Digital MarketingAGENCYHavas New YorkHarry Bernstein: Chief Creative Officer, Havas New YorkIsrael Garber: Global Executive Creative DirectorKeith Scott: Executive Creative DirectorPaul Johnson: Executive Creative DirectorPeter Gosselin: Creative DirectorJay Hunt: Creative DirectorAlexis Carr: CopywriterKeegan Sanford: Junior Art DirectorMatt DeCoste: Associate Creative Director (Web)Jess Davis: Associate Creative Director (Web)Allyn Scherr: Junior Art DirectorStuart Culpepper: Group Director, Product & ExperienceJames Cloughen: Digital ProducerTim Maleeny: President, Havas NY; Chief Strategy Officer Havas North AmericaCasey Ritts: Group Account DirectorElaine Purcell: Group Planning DirectorDarah Rifkin: Account DirectorDanny Wang: Director of TechnologyWilliam Lin: Solution ArchitectAngus Lo: User Experience TechnologistEric Nichols: Web Developer
