Another little bit of timeline history from the O-review site.
1975
Jim Jannard started the company out of the back of his trunk.
Oakley Grips were created
1978
Oakley Grip II released moving back to a traditional cylindrical design, but retaining unobtainium advantage.
1980
The Oakley Goggle was prototyped against Jannard better judgement. Appeared with rainbow strap and in a few colors.
Oakley Goggle soon replaced with the O Frame and Pro Frame geared for MX use.
Smaller Grip .5 and large asymmetrical Grip 3 released. Both were sold in bags rather than hanging boxes.
1981
F1 Grip System released utilizing a separate sleeve made from a stiffer unobtainium. Box was changed to a hexagonal format.
1982
B1-B Guidance System released similar to F1 with the separate sleeve, but in the style of the original grips.
1983
B2 Guidance System moves back to single grip component but retains doughnut to prevent rubbing against base.
L Frame was created in the same style of the O Frame, but designed for use over glasses.
Current goggles become MX variants (O/Pro/L Frame MX) and snow specific goggles are simply O Frame (Pro/L)
1984
Last grip is released, the O Wing Grip. No boxes are used and instead they fit in a clip.
First glasses released called Oakley Lites, then Factory Pilot Eyeshades. Designed based on O Frame, but with a thin frame and earstems.
