I remember hearing a story from some two decades ago, about a publicity stunt by one of the two - can't remember which - Pepsi or Coca-Cola.
The action was allegedly deployment of a gigantic balloon bearing the company's logo into Earth orbit, for publicity/advertisement purposes.
I can't give more details, as I only heard about as much. I don't even remember the source but I'm fairly sure it wasn't a very authoritative one - likely word on mouth. I can't find any references to the event so it's possible it was merely an urban legend or some other event misshapen by retelling. Thus the question - can anyone confirm or rebuke the story?
