=== Nagware ===
Nagware (also known as begware, annoyware or a nagscreen) is a pejorative term for shareware that persistently reminds the user to purchase a license.<ref>{{cite conference | first = Ian | last = Parberry | title = The Internet and the Aspiring Games Programmer | book-title = Proceedings of DAGS 95, "Electronic Publishing and the Information Superhighway" | publisher = Birkhauser | location = Boston | page = 2 | url = http://larc.unt.edu/ian/pubs/dags95g.pdf | date = June 1995 | url-status = live | archive-url = https://web.archive.org/web/20160304065316/https://larc.unt.edu/ian/pubs/dags95g.pdf | archive-date = 2016-03-04 }}</ref> It usually does this by popping up a message when the user starts the program, or intermittently while the user is using the application. These messages can appear as windows obscuring part of the screen, or as message boxes that can quickly be closed. Some nagware keeps the message up for a certain time period, forcing the user to wait to continue to use the program. Unlicensed programs that support printing may superimpose a [[Digital watermarking|watermark]] on the printed output, typically stating that the output was produced by an unlicensed copy.<!--examples of trialware that continues to work fully: Total Commander (nag screen)-->

Some titles display a [[dialog box]] with payment information and a message that paying will remove the notice, which is usually displayed either upon startup or after an interval while the application is running. These notices are designed to annoy the user into paying.
