At least eight companies have told ABC News they intend to pull their sponsorship of Ingraham's evening show.
Commenting on the link posted on her Twitter feed, Ingraham accused Hogg of whining about being rejected by the colleges and said that the rejection was predictable given his GPA (Grade Point Average) and acceptance rates.
With many people piling on the criticisms onto Fox News host Laura Ingraham, actor Michael Rapaport took it to the next level and personally attacked Ingraham. She said he was "whining" about not getting into some colleges, including UCLA, despite his 4.1 GPA.
Ingraham apologized to Hogg on Twitter on Thursday, after several advertisers had pulled their commercials from her show.
Ingraham apologized Thursday on Twitter, saying, "On reflection, in the spirit of Holy Week, I apologize for any upset or hurt my tweet caused him or any of the fearless victims of Parkland". She invited the student to appear on her program.
David Hogg is going after Laura Ingraham's advertisers, and it's working. "It's time to love thy neighbor, not mudsling at children", Hogg said on Twitter.

One driver said: "I drive people to their polling stations, wait of them and then take them back to collect the money". Sisi overthrew former president Mohamed Morsi of the Muslim Brotherhood in a 2013 uprising in the country.
But Hogg, the 17-year-old senior at Marjory Stoneman Douglas who has emerged as a leader in the nationwide movement for new gun laws following the shooting last month at the school, has been dismissive of Ingraham's apology and continued to call for an ad boycott of her show.
One of his latest moves was speaking at the March For Our Lives protest in Washington, D.C. over the weekend.
Various advertisers announced they will no longer support Ingraham's show.
Since then, these survivors have been the victims of attacks by conservative groups and Second Amendment advocates, including organizations such as the National Rifle Association and the Fox News network. "In our view, these statements focused on a high school student, cross the line of decency", the statement added.
Pressure from Hogg's 600,000 Twitter followers undoubtedly helped the companies come to their respective decisions.
"The only reason she is apologizing is because, at the time, a third of her advertisers dropped out", he told Inside Edition.
Nearly a year ago, more than 50 advertisers yanked their spots from Bill O'Reilly's Fox News show after it emerged that O'Reilly, Fox and its parent company had paid $13 million to settle five sexual harassment lawsuits. I think every week is a good week to apologize and not make these decisions to call out a 17-year-old like me who had to live through something like this and everyone else who has been rejected from college too - it is just terrible. After Sean Hannity supported Alabama judge Roy Moore in his campaign for the U.S. Senate, five companies removed their ads, including Keurig.
