TV channels schedule their programming to target different audiences throughout the day and avoid direct competition. Key scheduling techniques include inheritance, pre-echo, and hammocking programs around popular shows to boost viewership. Channels also target different demographics, with BBC One aiming for mainstream audiences, BBC Two focusing on educated viewers, and Channel 4 targeting teenagers to 50-year-olds. Imported programs are typically shown on Channel 4 and 5 due to BBC's limited budget to acquire foreign shows.
