It's always fun to see the famous icons and properties that reach public domain status in the new year. Some 365 days ago, the Steamboat Willie version of Mickey Mouse became free, which means they lost their copyright and anyone could use those specific images. (Which explains the subsequent cult horror movie featuring the early Mickey as a serial killer.)

So what's free in 2025? The biggest one may be the 1920's version of Popeye, the character many of us grew up watching on Saturday morning cartoons. For those whose tastes lean more to something European, the comic book character Tintin is up for grabs. So is Buck Rogers.

Not to mention the very first Marx Bros. talkie, "The Coconuts," which was made in 1929. 

Several famous books are also in the freebie range with the change of the calendar. Ernest Hemingway's "A Farewell to Arms" says farewell to being protected. Works by John Steinbeck, William Faulkner and Virginia Woolf are also included. 

The songs that came out of protection aren't exactly big hits today, but it means they can be performed without any issues. Among them - one that had a huge renaissance in the late 60s thanks to Rowan & Martin's Laugh-In: "Tiptoe Through The Tulips," which propelled the late Tiny Tim (aka Herbert Khaury) to 15 minutes of fame when he performed it on the show. 

And while the movie is still under copyright, the song "Singing In The Rain" no longer will be.
