TBWA chiat day announced that Guy Day—the Day of Chiat/Day—passed away in his sleep at the age of 77. Day had co-founded Chiat/Day with Jay Chiat in 1968.
The new agency, as we all know, went on to create some of the industry’s most iconic work, including Apple’s famous “1984” spot which turned the Super Bowl into “an advertising showcase.”

TBWA Wordwide CCO Lee Clow offered his thoughts of the agency’s co-founder: “Guy made me sane while Jay made me crazy. He taught me a lot of things, like how to understand Jay. I probably wouldn’t be here if it weren’t for Guy.”
