Its true perhaps that there was never much money to be made in just singing the blues and money talks (and sings).
But, a lot of acts did just that by taking elements of the blues and applying them to new forms of music that broadened the appeal of the blues. Led Zeppelin comes to mind as perhaps one of the best examples of this.
Also...on the bright side the influence of the blues is felt perhaps in more diverse areas of music today than ever before, so its overall impact is greater than ever I would say, even if true that there are also many other fish in the sea out there as well in terms of other forms of music.
