The Blue Planet
The first of the BBC's ocean series, and the template its sequel and the Planet Earth films all inherited.
The Blue Planet opens with a main title sequence of 31 seconds.
It arrived on BBC One in 2001, when A Question of Sport, Grandstand and This Is Your Life were also on the network.
