During the 1820s and 1830s, the increasingly sophisticated promotional techniques of contemporary publishers such as Richard Bentley, Frederick Mansell Reynolds, Thomas Tegg and, most significantly, Henry Colburn provoked some unease among poets and essayists, notably in a feeling that books were being marketed in the same way as more mundane products such as blacking, hair oil or lottery tickets. A series of essays and satires by literary figures such as John Clare, Thomas Hood, John Hamilton Reynolds, Robert Montgomery and Thomas Babington Macaulay directly compare the marketing tactics employed to sell consumer goods with the techniques used by what one might label the manufacturers in their own trade, the publishers. In Robert Montgomery's words, ‘Novels can be crammed down the public, just in the same style as … Kalydor, Blacking, Champagne, and other bottled wonders’; the likes of Colburn have made themselves indistinguishable from Alexander Rowland the younger, Robert Warren or Charles Wright. A discussion of brand marketing informed literary journalists' and satirists' discussions of the contemporary publishing business.
