With the exception of South Africa, they have been known as Pentax since 1957. Asahi wasn't used in the U.S. for a long time. Honeywell was on Pentax cameras. In other words, Pentax had the name recognition more so than Asahi Optical Company. One just didn't say, "I'm going down to the camera shop and buy me a Asahi Pentax Spot F" in the U.S.
Edit: "Pentax" was one of the names the Nippon Optical Corporation cycled through when searching for a name for their new camera in 1948, but ended up calling it the "Nikon" instead.
