Henry Mietkiewicz, the last person to interview Joe Schuster described the reason for the change as being "on orders from a New York editor".

Because there's no direct quote from Schuster he may have simply been speculating (e.g. as opposed to having been told) but I see no reason to assume that that's the case.



Prior to 1940, the newspaper was named the Daily Star. Siegel and Schuster had recently pitched the new and improved comic strip (shortly to be made into a nationally broadcast radio show) to the McClure Syndicate, who then resold the cartoon strip to hundreds of newspapers nationally.

Although the radio show's first episode accidentally described the newspaper as "The Daily Flash" this was hastily retconned by the second episode and on the day after the radio show was launched, the newpaper strip, comic books and radio show all changed to "the Daily Planet". 

In 1940 there were over 20 newspapers across the US named "The Daily Star" so in order to avoid the suggestion that Superman worked for an existing newspaper (or because of the connections with the very recently bankrupted "New York Star") it made sense for them to rename it.

As to the identity of the fabled "New York Editor", my guess would be that it was alleged Fascist Agent(!) and Owner / Editor-in-Chief of the McClure Syndicate, Richard H Waldo.

Why did DC Comics change The Daily Star to The Daily Planet?
I don't even clear about the differences between crosstalk and interference. Could you explain me please?

I just know that cross talk is the leakage power from other sources, whereas interference is the aliasing signal.

Could you tell me any other differences?
