It was the first day on the job for David Muir as the new Anchor of ABC's World News Tonight.

Muir had to work at holiday the first day out of the box.

At least his boss took time out from his holiday to wish him good luck:

Nuir opened the broadcast by wishing viewers a happy Labor Day and saying "it's an honor to begin this journey with you"

With Muir now anchoring ABC's newscast, it is back to the future for the network newscasts. All three net newscasts are fronted by middle age white guys.
