Vitaphone being used in the opening WB logo
Vitaphone discs were a sound-on-disc system used for Looney Tunes and Merrie Melodies shorts, particularly around the early 1930s until around 1939. Vitaphone discs were made of shellac, rotated at a speed of 33 1/3 rotations per minute, and were typically 16 inches in diameter. Because of their weight, fragility, and recently commercialised optic sound-on-film technology, the Vitaphone discs' usage was very short lived and was almost immediately phased out, with the Vitaphone brand becoming completely defunct in 1959.[1]
From 1931 until 1939, the opening Warner Bros. logo had Vitaphone's logo present, typically above the Warner Brothers shield. Looney Tunes cartoons that were made from 1939 until the mid-1960s had the Vitaphone logo replaced with "WARNER BROS." and then "WARNER BROS. PICTURES INC." later on. The Vitaphone brand also appeared on the bottom of every cartoon as a copyright notice from 1936 until 1960 (some Blue Ribbon reissues from the 1963-64 season originally released in 1957 also have the Vitaphone copyright disclaimer, although some reissues before that had WARNER BROS. PICTURES INC.). After 1960, it was changed to WARNER BROS. PICTURES INC. on the bottom. Later that year, VITAPHONE or VITAGRAPH (Merrie Melodies or Looney Tunes, respectively) was added onto the ending titles as a disclaimer from 1960-1969. VITAPHONE and VITAGRAPH were flipped during the last year of production, the 1968-69 season.
The opening only used in "I Wanna Play House"
