Interactive Program Guides (IPGs) are becoming the entertainment portal for TV viewers, and In-Stat/MDR expects the worldwide IPG market value to grow to nearly $1 bln by 2008. The high-tech market research firm reports that IPGs will be the “killer application” for enhanced interactive television services. IPGs will help end-users to find a TV program, movie or sporting event from among listings of thousands of available options, and then make it easy for them to select the program for viewing, tag it with a reminder for later, or even set up a recording to capture the show for time-shifting on a Personal Video Recorder.
