text: The readership waned during the 1990s with the rise of historical romances (and the switch of many Regency writers to the historical genre).  In the early 2000s, both Regencies and other historical romances lost popularity in favor of contemporary settings. The market in the United States was hurt by changes in distributing and retailing romances.  The last two major U.S. publishers to produce the shorter "traditional" Regencies regularly were Zebra and Signet.  This ended in 2005, when Zebra stopped their traditional Regency line, and early 2006, when Signet ended its Regencies.  There are some new "traditional" Regencies still published in the United States; some of the few publishers that still do so are Avalon Books, Five Star Books, and Cerridwen Press (Cotillion).  Previously published Regencies are also available through the second-hand book market, via Belgrave House (which publishes out-of-print books), and as e-book reprints.
  The Regency subgenre changed somewhat during the 1990s and 2000s, when authors began incorporating more sex into their novels, under pressure from a changing reader base.  While some long-time readers balked, publishers viewed the inclusion of sex scenes as a means of keeping the subgenre afloat. The goal was to appeal to a new generation of readers while still delivering the witty and clever plotlines loyal readers love. Regency romance authors such as Sandra Heath, Anita Mills, and Mary Balogh were the first to write about sexual relationships between the hero and heroine (or more rarely, between the hero and his mistress).
  Not all Regency romance novels are frothy period pieces. Such authors as Balogh, Carla Kelly, Sheila Bishop, Anna Harrington, and Mary Jo Putney all depict the underbelly of Regency society, exploring a variety of social ills in their novels.  Some authors feature seriously troubled heroes and heroines, who suffer from post-battle trauma, alcoholism, depression, and the like.
