Rosenberg hosted his own morning show, WAXY
790 The Ticket in
Miami, where he originally was paired with
O.J. McDuffie, formerly a
wide receiver with the
Miami Dolphins. McDuffie resigned his position with the station in the summer of 2006. Rosenberg's jokingly self-given middle name "Arthur" is a reference to former baseball player
Dave Kingman. When
Hall of Fame sportscaster Bob Murphy gave the lineups for the
New York Mets, he would always give Kingman's name as "David Arthur Kingman"; Rosenberg continues this
running gag on the Sports Guys by using Arthur as everybody's middle name.
Inflammatory television commentary Rosenberg frequently made inflammatory remarks on the
Imus show, which was simulcast on
MSNBC cable television. Among other things, he said on-air that
Venus Williams was an "animal," and that she and
Serena Williams would be better suited for
National Geographic magazine than for
Playboy. He also said that "faggots play tennis" and that the
U.S. women's national soccer team were "a bunch of juiced up dykes." Rosenberg was fired from the
Imus show after making crude remarks about Australian singer
Kylie Minogue's
breast cancer diagnosis. Chris Carlin replaced Rosenberg, although Rosenberg continued to call into the
Imus program. As a substitute sportscaster on April4, 2007, Rosenberg reported on
Rutgers University's
59–46 loss the previous evening to the
University of Tennessee, in the final game of the
NCAA Women's Division I Basketball Championship. This served as a lead-in to Imus and other cast members, who made comments that resulted in the cancellation of the program one week later.
Radio broadcasting, 2005–present Southern Florida Rosenberg began working at Miami-based
WAXY 790-The Ticket in November 2005. He and the station parted ways in March 2009. In September 2009, he joined South Florida radio station
WQAM. He was fired in April 2012 following a
DUI arrest and was replaced by
Dan Sileo. Rosenberg returned to the airwaves at
WMEN 640AM on August13, 2012. He was released by the station in December 2015 in what he called a cost-cutting move.
New York City Rosenberg returned to WFAN on Saturday, February6, 2010 to host a special Super Bowl preview show from Miami. On Saturday, March27, 2010 he again returned to the radio station hosting a show in
Port St. Lucie before the
New York Mets faced the
Washington Nationals. He also completed two weeks of fill-in work with
Kimberly Jones, Marc Malusis and
Anita Marks on WFAN in July 2010 from 10:00a.m. to 1:00p.m. for
Joe Benigno and
Evan Roberts, who themselves were filling in for
Mike Francesa from 1:00 to 6:30p.m. WFAN's Mark Chernoff told
Newsday of Long Island's Neil Best that he was very impressed with Sid's return to the FAN, but that there was very little he could do to make the temporary hosting in New York anything more than temporary. In 2011, Rosenberg became the weekday morning sports anchor for WFAN's sister station,
1010 WINS but left in 2012. That same year,
Craig Carton welcomed Rosenberg back, who
CBS had neglected to invite to WFAN's 25th Anniversary celebration. In 2015, it was reported that Rosenberg would be filling in for
Geraldo Rivera in August on
77 WABC. On January27, 2016, Rosenberg officially returned to New York radio as co-host of
The Bernie and Sid Show of 77 WABC with
Bernard McGuirk. On March8, 2018, Rosenberg and McGuirk signed contracts to replace the retiring
Don Imus of the
Imus in the Morning show. On December2, 2022, following McGuirk's death,
Bernie and Sid in the Morning became known as
Sid and Friends in the Morning. On October 27, 2024, Rosenberg spoke at
President Trump's rally at
Madison Square Garden, railing against former Senator
Hillary Clinton in particular and Democrats in general. In March 2026, Rosenberg called New York City Mayor
Zohran Mamdani an "America-hating, Jew hating, Radical Islam cockroach" in a post on the
social network X attempting to turn President Trump against Mamdani. Rosenberg later deleted the post and apologized on-air for the remarks. ==Personal life==
