Which add slogan was on television first?

It's impossible to say definitively which ad slogan was on television first, as the earliest television commercials were broadcast in the late 1940s, and records of exact slogans used are often incomplete.

However, we can look at some early examples:

* Bulova Watch: One of the first commercials aired on television in the US was for Bulova watches. While the exact slogan used is unknown, it likely featured the brand name and a simple message about accuracy and reliability.

* Kellogg's: Another early adopter of television advertising was Kellogg's cereal. Their commercials often emphasized the nutritional value of their products.

* Ford Motor Company: Ford was also an early advertiser on television, showcasing their cars and emphasizing their features.

It's important to note that advertising on television was still in its infancy in the late 1940s, and slogans were often simple and direct. It was only in the 1950s and 1960s that advertising became more sophisticated and memorable slogans became more prevalent.

Therefore, while we can't pinpoint the absolute first slogan, these early examples offer a glimpse into the evolution of advertising on television.
