Wish I could agree with you, Erica—but commentor Algernon on this post correctly diagnoses the P-I’s fatal move:
Three days after the P.I. removed Zippy from the comics pages, Hearst announced he was selling. There is a connection. Zippy is on the grassy knoll.

No Zippy, No Peace!
i canceled my subscription to the PI as soon as i saw that Zippy was gone. I’ll still read Zippy online, but it just isn’t the same, dammit.
Only reason I ever wrote a letter to a newspaper was to complain that Zippy was gone from the P-I. Turned out to be moot, but still?
Is the P-I up for sale yet?
Maybe Zippy could buy them out?
