Is there any way I can find out the year a slogan or jingle originated for a product? Specifically, I am curious to know when Texaco (gas stations) first ran the “always trust your car to the man who wears the star” OR “you can trust your car to the man who wears the star” slogan ran on TV or radio. On an episode of MASH, Hawkeye alludes to this ad campaign by paraphrasing the slogan. But, could this motto date back to the Korean War? I wager it’s possible, but I can clearly recall them running this slogan with a jingle in the 1970s*. I am curious to know the year of origin.
*It is always possible the jingle or motto came and went and returned once more in the 1970s.
