Sidney Arthur Rosenberg is an American radio personality.

Rosenberg's radio career started in West Palm Beach, Florida, where he hosted the syndicated sports radio program The Drive in the late-1990's. In 2000, he moved to New York City to co-host WNEW-FM's morning show, the Sports Guys. A year later, he joined the Imus in the Morning program, where he became their sports reporter. Several months after joining the Imus show, he became the co-host of the midday show on Imus' flagship station, WFAN. He would hold both positions until 2005. For several years, he also hosted the radio pre-game shows for New York Giants home games.

Rosenberg is no stranger to controversy. Among other things, he would say on-air that Venus and Serena Williams would be better suited for National Geographic Magazine than for Playboy, that "faggots play tennis" and that the U.S. Women's Soccer Team were "a bunch of juiced up dykes." He would eventually be removed from the Imus show in May 2005, after saying in regards to Kylie Minogue's battle with breast cancer, that "She won't look so pretty when she's bald with one titty."

Among other personal problems, Rosenberg has also been involved with a lawsuit for stealing DirecTV, and was taken into a rehabilitation center earlier in 2005 for a triple addiction to crack cocaine, alcohol, and gambling.

Rosenberg would leave WFAN altogether on September 12, 2005. He did so after failing to show up to host the Giants' pre-game show on September 11, 2005 (he made an appearance for FHM in Atlantic City that weekend). As a result of the no-show, management at WFAN gave him the option to resign from the station, which he did. The New York Post reported that he would likely have been fired if he did not resign.

Rosenberg currently works for WAXY in Miami, Florida, where he hosts a show on weekends and serves as a fill-in.
