And now, with major anchor changes underway at ABC News and MSNBC, I'm certain. The TV industry has a fresh chance to build anchor lineups which look more like America, allowing journalists of color a shot at the highest-profile jobs. But so far, executives don't seem particularly inclined to blaze any new trails.
