At the end of the day, advertising is a talent business. That's why Ad Age is seeking out the best places to work in several of the industries we cover: ad agencies, ad tech and media.

We'll celebrate the top-ranked companies in each sector in our Best Places to Work 2014 report, out in November. To enter, register here: www.adage.com/bestplaces The deadline is Aug. 18.

Ad Age works with Buck Consultants, which has nearly a century of experience in employee and human-resource consulting, to conduct employer and employee surveys which identify the companies with the best benefits and the most-engaged employees.

Companies ranked on the list will have the opportunity to promote their unique cultures, as well as understand how they stack up against competitors. They will be given access to candid feedback from employees, and each company will receive a complimentary report summarizing responses from participants across the ad agency, ad tech and media sectors.

In 2012, Ad Age highlighted 40 of the best places to work in advertising and media. Hailing from around the country, these companies, from big shops to independents, were recognized for their outstanding benefits, nurturing cultures and standout spaces.

Among the highlights: Edelman, which offers ten-year veterans a paid three-week sabbatical; Horizon Media, which has sent teams of employees to Central America with Habitat for Humanity; and Colle & McVoy which has an "Ad Gyver" award recognizing the teams behind the best work of the quarter with an all-expenses-paid happy hour.
