With the increase use of the "On Demand" feature, more channels are providing content, including HBO. Because HBO is a pay channel, customers need to order the content. Once you have the channel, you can watch the "On Demand" content whenever you want -- On Demand is a free service for HBO subscribers. The exact programs vary from month-to-month, depending on what HBO provides. For example, recent episodes of their shows "Entourage," "True Blood" and "Game of Thrones" may be available.
Dial the number of the cable or satellite company you subscribe to. Ask them to add HBO to your television package.
Press the "On Demand" button on the remote. The button used depends on the service. For example, Comcast remotes have an "On Demand" button.
Scroll the list of "On Demand" content until you find HBO. Select a show to watch.
Some cable companies also offer an online version on HBO On Demand called HBO Go, which is free with your HBO subscription. Check with your cable or satellite provider to see if they offer that service.
