American Idol was a pioneer in reality talent shows, however like everything in life, it's popularity has decreased due to new and more elaborated formats that allow to discover either a wider range of talents or better quality.
When American Idol started it was a vehicle to let undiscovered singers become stars, many of their participants were singers without any vocal training and the figure of the vocal coach was a shadowy element that moved behind the curtains.
With the new format of talent shows such as The Voice, X Factor and other kind of talent such So you Think you can dance, The Singout and so many others, the voice trainer became a more prominent role and made people aware that performers must train their talent.
This resulted in better and more qualified performances, that increase the interest of the viewers in this kind of shows.
American Idol also suffered from the so many changes of cast, with so many misses and credibility, chemistry gone out the window and even changes on their logo and overall brand.
American Idol may be a dying franchise but only the time will say it definitely.
