Jack in the Box (first era)
Jack in the Box was founded on February 21, 1951. The very first location opened in San Diego.
Jack in the Box Hamburgers
In 1971, Jack in the Box was renamed as Jack in the Box Hamburgers. The word "Hamburgers" was added into its name.
Jack in the Box (second era)
In 1978, Jack in the Box Hamburgers was renamed as Jack in the Box. "Hamburgers" was dropped from its name and a new logo was introduced. Changes are that the red box was added with the picture of the print version of the mascot Jack. Under that is the name written in a new font. There was a prototype version of the next logo which has a red diamond showing half of Jack.
On March 20, 1980, the company modified their 1978 logo. Changes are that the name is basically written in the same font but this time inside the red diamond. The wordmark is stacked and Jack was removed from the logo. In 1986, Monterey Jack's changed their name back to Jack in the Box and the 1980 logo returned. This logo is no longer in use as of March 16, 2009, but it can still be seen at some older locations.
To help chase their then-target crowd of affluent "yuppies", Jack in the Box was rebranded as the more-upscale Monterey Jack's on May 20, 1985. This was a disaster and returned to the original name in 1986.
Jack in the Box (third era)
On March 16, 2009, Jack in the Box launched its new identity. Following this, it began with a series of Super Bowl advertisements in which Jack gets hit by a bus, followed by his injury. In the fourth one, Jack gets rid of the 1980 logo and puts the new one on when new identity was launched.
