TiVo (/ˈtiːvoʊ/ TEE-voh; Television Input / Video Output) is a digital video recorder (DVR) developed and marketed by TiVo Inc. and introduced in 1999. TiVo provides an on-screen guide of scheduled broadcast programming television programs, whose features include "Season Pass" schedules which record every new episode of a series, and "WishList" searches which allow the user to find and record shows that match their interests by title, actor, director, category, or keyword. TiVo also provides a range of features when the TiVo DVR is connected to a home network, including film and television show downloads, advanced search, personal photo viewing, music offerings, and online scheduling.
Since its launch in the United States, TiVo has been made available in Australia, Canada, Mexico, New Zealand, Puerto Rico, Sweden, Taiwan, Spain, and the United Kingdom. Newer models, however, have adopted the CableCARD standard, which is only deployed in the United States, and which limits the availability of certain features.
