New York ( CNN ) -- Is Rush Limbaugh becoming a relic , a human version of `` Mad Men , '' except without the style or cool clothes ? Has Limbaugh become as dated as Jazzercise or `` Macarena ? '' All you need to do is look at the bottom line to see that Limbaugh is in trouble . Limbaugh once raked in the big bucks for his radio syndicator , Cumulus . But last week , Cumulus CEO Lew Dickey made it clear those days are over . Dickey reported that Cumulus had lost millions of dollars in ad sales because many advertisers no longer want to be associated with Limbaugh . According to Dickey , advertisers began to pull away from Limbaugh after his February 2012 comments in which he infamously called law student Sandra Fluke a `` slut '' and a `` prostitute '' after she testified before Congress advocating birth control be covered by health insurance . Limbaugh 's despicable comments were met with an avalanche of outrage and calls for corporations to stop advertising on Rush 's show . How badly did this advertising boycott hurt Limbaugh 's show ? Well , according to the radio industry magazine `` Radio Ink , '' 48 of the 50 network advertisers for Cumulus radio have excluded Limbaugh 's show from their ad orders . I 'm no media expert , but that sounds really bad for Rush . What was Limbaugh 's response ? Was he contrite or remorseful ? Nope . Instead Limbaugh lashed out last week at young women again by asserting that the reason ad sales fell off was because : `` The media buyers at advertising agencies are young women , fresh out of college-liberal feminists who hate conservatism . '' Not only is this comment sexist on its face , remarkably Limbaugh apparently does n't believe that his past antics have contributed to Cumulus ' lost ad sales . In fact , a close associate of Limbaugh voiced similar sentiments to Politico last week , arguing that the loss of ad sales is not because of Limbaugh , but because the Cumulus owned radio stations are underperforming when compared with other talk radio stations . How did Limbaugh get to this place ? Times have changed . Call it being PC or being more sensitive , no one can dispute that what was once acceptable in our society as humor and commentary is no longer . Sure Rush has a big audience and remains ahead of other talk radio hosts , but the advertisers who abandoned Rush appear to be on to something . Let 's take a quick stroll down memory lane of Limbaugh 's remarks -- all of which I wish I could have surgically removed from my memory : . 1 . `` NFL all too often looks like a game between the Bloods and the Crips without any weapons , '' a comment Limbaugh made while sharing his `` insight '' on professional football . 2 . `` He is exaggerating the effects of the disease ... It 's purely an act . '' -- Limbaugh mocking actor Michael J . Fox 's struggles with Parkinson 's . 3 . Limbaugh claimed that President Barack Obama was disappointed that Hurricane Irene , which killed 40 people , was n't worse : `` Obama was hoping this was going to be a disaster as another excuse for his failing economy . '' 4 . `` Forget calling them the NAACP . They are now the R-A-C-I-S-M. NAACP equals racism , '' Limbaugh 's comments defending the smear of Shirley Sherrod by right-wing media . There are many , many more examples of these `` Limbaughisms '' through the years . Looking at these comments makes you wonder why it took so long for advertisers to wake up and smell the bigotry . So what happens if Limbaugh is booted from his current syndication deal ? Limbaugh will probably find a new home on a lesser terrestrial network or possibly SiriusXM radio . My hope is that Limbaugh ends up as the in-store deejay at a Virgin megastore in a strip mall in the middle of nowhere . But then again , why should those shoppers be subjected to Rush 's rants ? Regardless where he turns up , Limbaugh will likely not be as relevant to the national media as he is now . All you have to do is look at the career of radio host Don Imus . Imus was fired from CBS radio in 2007 after a national furor erupted over his comments regarding the Rutgers women 's basketball team that were almost universally considered racist and sexist . While Imus later found a new radio home , he was no longer the same media mover and shaker . And while Imus is still on five days a week , when is the last time you heard the national media quote Imus ? Imus may just be Limbaugh 's `` ghost of Christmas future . '' The opinions expressed in this commentary are solely those of Dean Obeidallah .
Rush Limbaugh and his radio network are at odds . The conservative talk show host has been a vocal critic of President Barack Obama for the past several years. He says America has changed , Limbaugh has n't and his time is past .
