 ABC Family was the first network since ABC to show all the accurate introductions for each of the show's seven seasons.For the broadcast syndication and Disney Channel airings between 1997 and 2007, the opening title sequence from season four (along with a slightly modified version of the theme music from that season) anachronistically replaced the title sequences for the first three seasons, while the opening titles for seasons four through seven were kept intact.It is one of many television shows to take place primarily in the Philadelphia area and makes multiple local references.
