Beginning in the 1990s, some shows began with a "cold open", followed by a title sequence and a commercial break.

This scene was included in the title sequence of all later series.

The title sequence would stay constant for the next six years.

This title sequence was used only during seasons 1 and 2.

Each opening title sequence has differences in it from the others.

It is the first episode of the series to open with the show's title sequence.

For instance, the title sequence of the 1968 film Oliver!

Other than the title sequence, the series used little external shooting.

It appeared in the title sequence of the original seven seasons.

John Wilson did the animated title sequence for the start of the film.
