As women gain greater visibility in advertising and in the media, their voices have increased, but it’s been in the past 20 years that the gender of the person in front of the camera has been an increasingly important factor.

Women have been making up more than a third of directors and directors of the world’s largest advertising agencies, and are now the majority of the directors in the world of the most influential media companies, according to a new study.

In a global survey by the Nielsen Group, women were the biggest gender influencers in advertising in 2015, representing nearly half of all respondents, up from less than 10 per cent a decade earlier.

And the report’s authors, David McGlothlin and Elizabeth McNeill, say the gap between what women say they want from advertising and what they actually see is widening.

In the years since, the gender gap in terms of the representation of women in the advertising industry has grown, and the gap has widened between women and men.

The Nielsen study says it’s difficult to say how much of the gender imbalance in the industry is due to women’s greater ability to speak out, or simply due to how advertising is perceived.

There are no clear data to link the gender gaps in the two categories, according a Nielsen spokeswoman.

In the last year, the number of female directors and chief executives has grown by about 60 per cent, while the number for women in leadership positions has also grown.

The survey found that women are now at the top of the industry, with about 55 per cent of global ad executives being women, up almost 20 per cent from 2015.

The report says the gender difference is more pronounced in digital media, with digital ad revenue growing at double-digit rates since 2011.

Digital revenue is growing at about double the rate of advertising, but advertisers are still paying less.

But the report also points to some other trends in the business world, including increased access to technology, as well as a shift towards smaller teams, which are now increasingly used to running ad campaigns.

In fact, the report says, women now hold the majority control over the content of online ads and the decision to publish a particular ad online is largely up to the ad agency.

It also found that advertisers are more likely to use female voices, and to hire female candidates in high-tech roles, which is partly because women are less likely to be able to negotiate salary and benefits packages with companies that do.

The researchers say the biggest obstacle to female-dominated ad agencies is often the lack of women on the boards of their companies.

That can mean that the women who are on the board of a company that has a female executive director are often not the ones who ultimately run the company.

“It’s not uncommon for women who have been working in the ad industry for a long time to feel that they don’t have the same voice as those who are in the boardroom, and they don.

It can be a frustrating situation,” said McGlowlin.

The study’s authors say it’s time to re-evaluate the role that women play in the management of a business.

Advertising has been dominated by men for decades, and there’s still a lot of work to do to close the gender wage gap, they say.
