Some examples of broadcast television guides are TV Guide, TV.com, TitanTV, Huffpost TV and Zap2It. TV Guide is the most well known of the group because it has published a biweekly magazine dedicated to television listings and news since 1953.
There are only minor differences between most broadcast television guides. TV Guide's listings have a social "I'll Watch" feature. TV.com's listings allow the user to filter shows by genre. TitanTV's listings use different background colors based on the type of show. All of the television guides are in a grid format that organizes shows by date, time and channel. The guides also indicate which shows are new or in high definition.
