Romper Room was also franchised internationally[citation needed] at various times in Canada, the United Kingdom, Japan, Finland, New Zealand, Puerto Rico, Paraguay, Australia,[3] Argentina and Greece.

Romper Room was a rare case of a series being both franchised and syndicated, and some local affiliates—Los Angeles and New York being prime examples—would produce their own versions of the show instead of airing the national telecast.

Some affiliates, starting with KWEX-TV in San Antonio, translated the scripts into Spanish for local airings.

[citation needed] For example, when Edna Anderson-Taylor left the KSL-TV version of Romper Room, the waiting list was over three years long.

The hostess and her group of children then embark on 30 or 60 minutes of games, exercises, songs, story-telling and moral lessons, which were regularly accompanied by background music.

The young cast, which ranged from four to five years old, was rotated every two months, with many of the hostesses having prior experience working with small children and many being former kindergarten teachers.

At the end of each broadcast, the hostess would look through a "magic mirror"—actually an open frame with a handle, the size, and shape of a hand mirror—and recite the rhyme, "Romper, bomper, stomper boo.

She would then name the children she saw in "television land", saying, for example, "I can see Kathleen and Owen and Julie and Jimmy and Kelly and Tommy and Bobby and Jennifer and Martin" and so forth.

About 100 of these skits — each running three to five minutes — were produced for insertion into local Romper Room programs; the host would introduce each segment and comment after its conclusion.

Jeffery's shows were filmed at KTVU in Oakland, California (the longtime San Francisco Bay Area affiliate of the series).
