Self publishing
The market for self-published books is booming. Of the fifty top-selling Amazon eBooks as of February 22, 2022 at 9:00pm (and yes, the list is updated hourly,) 19 are self-published. Another 11 are published by Amazon in-house imprints Montlake, Lake Union, and Thomas & Mercer. Just 20 are from traditional publishers like Penguin or Harper Collins. KDPRocket reports that the best-selling of the indie books (The Rake, by L.J. Shen) has $418,471 in monthly ebook sales, and the last of the indie books (The Plains of Laramie by C.J. Petit) has $42,093 in monthly ebook sales. Each book is also available in softcover formats, as well, so the total is actually higher.

Copyright vs. Plagiarism
Plagiarism is thus both broader and narrower than Copyright infringement: (1) directly copying someone's work without attribution is a violation of their copyright and is plagiarism; (2) directly copying someone's work with attribution is still a violation of their copyright, but is not plagiarism; (3) copying someone's ideas without attribution is not a violation of their copyright, but is plagiarism.
