Women filling the roles vacated by prominent men after sexual harassment accusations

It's happening in media, politics, and entertainment.

— -- A number of the positions left open by the dismissal of prominent men as the result of sexual harassment and assault allegations have been filled by women.

The men have issued a range of statements in their defense, some admitting to some wrongdoing or none at all, but that hasn't slowed the dismissals. In the past three days, for instance, four of those powerful roles have been reassigned.

Hoda Kotb made history on NBC's "Today” show Tuesday by becoming a part of the show's first female-only anchor duo after replacing Matt Lauer, who was fired as a result of a sexual harassment allegation.

The changes this week are just the latest wave, following other replacements last month.

Women’s empowerment groups are celebrating the promotions, but also being careful not to place all the credit for the changes on the alleged abuses by men.

“What we are seeing with these latest announcements is the recognition of highly qualified media professionals who have proven themselves and are now receiving the opportunities they have earned,” Becky Brooks, the executive director of the Alliance for Women in Media, said in a statement to ABC News.

“To suggest that these most recent promotions were based on anything other than the talents and tenure of these journalists would be to diminish the incredible collective experience, knowledge and skill that these women bring to their new roles,” Brooks said.

Audiences appear to be responding to the news, with each move being widely praised and shared on Twitter.

When Kotb's promotion was announced, co-host Savannah Guthrie said it "has to be the most popular decision NBC News has ever made," and Twitter users seemed to agree, with the hashtag #SavannahHodaTODAY trending shortly after.

As for Wagner, she tweeted that she's excited about her move to "The Circus," later sharing a tweet throwing some shade at a report that didn't name her in the headline about Halperin’s being replaced.
