A non-exhaustive list of legally distinct brands in DC Comics
This is mostly for me to reference later
stand-in for Coca-cola or Pepsi-Cola
First appearance: Detective Comics 1937 #645 (Dective Comics 1937 646, Robin 1993 40, Robin 1993 57)
Stand in for Coca-cola or Pepsi-Cola
First appearance: Action Comics 1938 663 (JSA 2025 14, cover variant)
(No idea where this comes from, but it looks like it's from the latter half of the Robin 1993 run, amazing synergy with his expression)
stand-in for Twitter, does this making "chirping" the equivalent of "tweeting" and "chirp" the equivalent of "tweet"?
Teen Titans 2014 2, Nightwing 2016 16
stand-in for Archive of Our Own (AO3)
