Have you ever noticed how, when viewing TV prints of various cartoon shorts (including many Looney Tunes, Tom and Jerry, and Popeye entries), the title and credit sequences appear zoomed out and placed in a set of black or colored borders? I could never really figure out why that was done. Also, when did this become a trend? I've seen some really early TV syndication prints of some shorts that were later given the windowbox treatment for their respective titles (Fresh Hare, The Bowling Alley-Cat, Kitty Foiled, just to name a few examples) particularly in the Turner prints. Are said borders really necessary?
