What if Fox Broadcasting Company first aired in 1942?

In 1942, the DuMont Television Network first aired. The Network aired for 14 years until in 1956, the DuMont Television Network last aired, and did not air ever again.

30 Years Later, 20th Century Fox launched a broadcasting channel called the Fox Television Network. After Disney bought 21st Century Fox's film and television studios, all of their channels are kept by Fox Corporation.

For this AU version, let's imagine if DuMont and Fox fused into the same network.
