When we look back on television in 2016, the so-called series finale of Fox’s “American Idol” will be remembered as one of the best live entertainment programs of the year, along with the same network’s dazzling production in January of “Grease Live!” At a time when broadcast television is struggling against ever-increasing competition to somehow distinguish itself as something special and remain at the top of Media Mountain it seems to me that Fox should have it all figured out. Keep these events coming -- and for God’s sake don’t wait too long to bring “Idol” or something like it back.
