“All publicity is good publicity” (“There is no such thing as bad publicity”)

American showman P. T. Barnum (1810-1891) is often credited for having said, “I don’t care what people say about me as long as they say something.” “He doesn’t care what his enemies say about him so long as they say something” was written about a person in 1879; this was said to be “like Barnum.” It’s not known if Barnum ever said the quote for which he has long been attributed.
 
Oscar Wilde (1854-1900) wrote in the novel, The Picture of Dorian Gray (1910), something similar to the Barnum-attributed remark:
 
“It is silly of you, for there is only one thing in the world worse than being talked about, and that is not being talked about.”
 
“There isn’t any such thing as bad publicity” has been cited in print since at least 1916. “Any publicity is good publicity” has been cited in print since at least 1925. “‘There isn’t any such thing as bad publicity,’ or, to express the same idea in reverse, ‘all publicity is good publicity’” was written in 1939.
 
The Irish writer Brendan Behan (1923-1964) added a memorable variation when he said in 1960, “There’s no bad publicity except an obituary notice.”
 
     
Wikiquote: The Picture of Dorian Gray
The Picture of Dorian Gray (often mistakenly referred to as The Portrait of Dorian Gray) is the only published novel written by Oscar Wilde, first appearing as the lead story in Lippincott’s Monthly Magazine on 20 June 1890. Wilde later revised this edition, making several alterations, and adding new chapters; the amended version was published by Ward, Lock, and Company in April 1891. The basic theme is of a man whose portrait ages while he remains young, leading him to debauchery.

The saying is widely attributed to P. T. Barnum. It perhaps originated as a counter-proverb rebutting “Not all PUBLICITY is good publicity”—or vice versa.

Every business man has to advertise, even if it is only by a sign over his door. All advertising is good. P. T. Barnum said: “I don’t care what people say about me as long as they say something.”

The second dealer had refused to give a local newspaper some information concerning the coal situation, when asked for an interview, on the specific ground that it wouldn’t be “good publicity” for him. And this remark reported by the reporter to the first-named coal man, caused him to snort with disgust.
 
“Good publicity?” he repeated. “What does he think he means by good publicity? There isn’t any such thing as bad publicity.”
