Background: Tribune Broadcasting is the broadcasting arm of Tribune Company. It began in the 1930s with the sign-on of WGN-AM in Chicago ("WGN" stands for "World's Greatest Newspaper", slogan of thecompany's namesake, the Chicago Tribune). It entered television in 1948 with WGN-TV in Chicago and WPIX-TV in New York (the "PIX" in WPIX is for the New York Daily News's then-slogan, "New York's Picture Newspaper"). It grew by acquiring more stations (such as Duluth's KDAL (now KDLH) in 1960, being Tribune's first station west of the Mississippi, Denver's KCTO in 1966 (now KWGN), being kept by Tribune after KDAL's sale, and Los Angeles's KTLA in 1985, formerly owned by Gene Autry). From 1995 to 2006, it owned a minority interest in the now defunct The WB network. During The WB's existence, Tribune exited the radio business (excluding WGN-AM), bought out a company called Renaissance Broadcasting (no relation to Renaissance Pictures), and bought several other stations (such as Seattle's KCPQ). Many of its WB stations were sold not too long after the inception of it's successor, The CW (the aforementioned stations, with one exception, all went with The CW at its launch). Anyway, now to the logos:

Note: Prior to this logo's usage, the logo used for newscasts was the then-current Tribune Entertainment logo, with "ENTERTAINMENT" replaced with "BROADCASTING".

Nicknames: "Zooming Tribune Text", "The WGN Logo"

Logo: In widescreen, we see a changing purple/pink/blue background with "TRIBUNE" in its corporate logo font, moving in different directions when it changes scenes of the BG. Then the text:
