Certainly it works and even commercials on music stations work. If they didn't you can bet it would have charged long before now.
No matter the fancy paperwork or justification used, it all gets back to results. Results were either better, worse or the same as campaigns in the past and it's those results that determine if that ad agency has a solid customer or not.
One thing not mentioned so far: length of life. If you jump back to the 1950s and 1960s, people generally did not live as long as today. The same can be said of the 1970s, 1980s and each future decade. The fact is we simply live longer. Age 50 meant you had few years left 60-70 years ago. 50 is much more mid-life now. While the 50+ has been considered 'too old' and still is, it might be easing in coming years as the numbers increase simply due to population trends and length of life.
