Jack in the Box (first era)
Jack in the Box was first introduced in 1951
Jack in the Box Hamburgers
Then it was renamed as Jack in the Box in 1978. The logo was shown in the tacos commercial from 1976.
Jack in the Box (second era)
On March 20, 1980, Jack in the Box then rebranded their logo. Changes are that the name is basicly written in the same font but now inside the red diamond. Also, Jack was removed from the logo. In 1986, Jack in the Box returned to both its own name and its 1980-1985 logo. This logo may no longer be current, but can still be seen at some locations. It is also still used on drinks. The logo was ended on March 15, 2009.
To help chase their then-target crowd of affluent "yuppies", Jack in the Box was rebranded as the more-upscale Monterey Jack's in 1985. This was a disaster and the original name was restored in 1986.
Jack in the Box (third era)
On March 16, 2009, Jack in the Box launched a new identity. It began with a series of Super Bowl advertisements in which Jack (the mascot) is hit by a bus and injured. In the fourth one, Jack gets rid of the old logo and puts the new one on, thus launching the new identity.
