For my research I analyzed more than 8,000 commercials and print ads. I divided these into 11 branches and chose a number of suppliers from different branches to make more extensive case studies.
Next, I looked at some general trends and specific topics.
Visual examples, and artwork can be found at the bottom of each of the 6 main menu pages, (like the green ones below).
These are all (print) ads, used to target LGBT customers/employees.
