HBO Ident

Unusually for a cable channel, HBO has kept the same basic logo for most of its existence – but it has gone through at least one major change. HBO's 1970s-era logo had the "O" overlapping the "B", and is accompanied by a three-stripe rainbow. Both of these were phased out by 1982. This ident is simple – a tumbling model "HBO" keyed over a rostrum shot of the earth.
