No matter when he announced, Americans weren't going to the TV to watch. By going on 3 networks that early in the morning, it ensured all those networks had their own coverage and would be likely to have the story on their news segments throughout the day. Then others will pick it up as well.

He had nothing to be gained by waiting. But he did catch millions who watch one of those 3 news programs each morning before work. Not only is that his target audience (workers) and caught all 3 networks at the same time, but the total that watched was in the millions. People watched him because they were already watching the show as part of their routine, thereby he reached millions who may otherwise not have watched his announcement - and important achievement.
