Back in the very late 80s to 90s, there was a programming started on Friday evenings called TGIF, or, Thank God/Goodness It's Friday. These shows were family-friendly sitcoms in a variety of genres and circumstances.
But what made these TV shows stand out were their opening jingles/themes. It doesn't matter what part of the house one was in, if your TV was up high or could be heard, and one of those opening themes came on, you knew exactly which show was coming on!
