If you're involved in the world of television or radio broadcasting, you may have heard of dayparting. Dayparting is the practice of separating out the day into different time periods. Different demographics will typically be watching or listening at different times, so accurate dayparting is essential when deciding when to broadcast different types of programmes. Typical dayparts are breakfast, daytime, prime time, late night and overnight. It is worth noting that due to cultural differences, dayparts are different in different countries.
