HBO Sign Off

HBO did not begin broadcasting 24 hours until 1981. Therefore, it signed off each night with this animation, a subtle message to the audience that it was time to go to bed. Abstract and crude 1970s-era animation abounds in this one. Note the logo at the end – it's the 1970s "overlapping O" variant, but with the message "HOME BOX OFFICE FROM TIME/LIFE" at the bottom, a reference to its parent company. The TIME/LIFE bit was an effective piece of marketing, since it tied in the newborn HBO with the trusted Time/Life magazine brands.
