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)
To help avoid confusion with the toy, Jack in the Box was rebranded as Monterey Jack's in 1985. Then the original name came back alive in 1986.
Jack in the Box (third era)
In 1986, Jack in the Box returned 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.
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.
