The mystery $7,000 bid for the jockstrap worn by actor Russell Crowe in Cinderella Man, sold during the actor's "Art of Divorce" auction, went to British satirist and US TV host John Oliver.
Oliver, who bought the jockstrap along with a few other items, purchased the memorabilia in an attempt to save the former global chain Blockbuster.
During Last Week Tonight on Sunday, Oliver revealed his shock to find there were some independent Blockbuster stores operating in the northwest US state Alaska.
This follows news in March that one of the state's Blockbuster's few remaining brick and mortar stores is shutting down.
Blockbuster, a movie and DVD renting chain that announced bankruptcy in 2010, survived in some states because communities had a lack of access to high-speed internet.
On Sunday, Oliver revealed he was the mystery buyer that purchased the jockstrap and it was done to help Blockbuster.
"We absolutely did [buy it]," Oliver joked before yelling "are you not entertained" in a throwback to Crowe in Gladiator.
"What happened, it was 4am over here and you know what happens when you start late night shopping.
"You wake up the next day thinking shit, what did I just buy... we didn't just get a jockstrap, we got a bunch of pointless Russell Crowe memorabilia and I can think of no more fitting place for them to reside than an Alaskan Blockbuster."
OIiver tweeted out a photo of himself standing next to the jockstrap with the invitation: "Hey, Blockbuster! Come and get it!"
The photo also showed other memorabilia, which included a satin robe from the aforementioned movie Cinderella Man, a Denzel Washington director's chair from American Gangster, a hood from Robin Hood and a vest worn in Les Miserables.
Oliver gave Blockbuster 48 hours to contact the show to collect the memorabilia.
At the height of its popularity, Blockbuster had more than 9,000 stores across the US before streaming services stole its customer base.
