Adweek

In 1990, Affiliated Publications Inc., which publishes The Boston Globe, agreed to acquire 80 percent of the outstanding common stock of A/S/M Communications Inc., which published Adweek. The magazine stabilized in the 1990s under Verenigde Nederlandse Uitgeverijen's BPI Communications (VNU, later known as Nielson).

In April 2008, Alison Fahey, Adweek's editor of ten years, was promoted to publisher and editorial director. She was replaced as editor by Mike Chapman, formerly of the Economist Intelligence Unit and eMarketer.

On June 2, 2020, Los Angeles–based investment firm Shamrock Capital acquired Adweek from Canadian private equity firm Beringer Capital, which had acquired Adweek in July 2016.

On July 26, 2023, Will Lee was announced as Adweek's CEO.

On November 30, 2023, Zoë Ruderman was announced as Chief Content Officer and Drew Schutte as Chief Revenue Officer.

On January 15, 2015, after the acquisition of its previous parent, Mediabistro, by Prometheus Global Media, Adweek formed the "Adweek Blog Network," which consists of several B2B blogs about aspects of the mass media industry. They include AgencySpy, which focuses on advertising news, TVNewser, which focuses on cable and broadcast TV and streaming news and TVSpy, which focuses on local television news. Other sites included FishbowlDC, focused on politics and the media, FishbowlNY, focused on New York City media, GalleyCat, which focused on book publishing, LostRemote, which focused on social television, PRNewser, which focused on public relations and SocialTimes, which covered social media platforms.

The most notable member of the blog network is TVNewser, which focuses on the American news media and broadcast industry. The site was founded as CableNewser by then–Towson University student Brian Stelter in January 2004, who maintained the site until joining The New York Times as a media reporter in July 2007. Former MSNBC producer Chris Ariens took on the role of editor in 2007 and is now Adweek's SVP and Editorial Director. TVNewser is highly-read within the broadcasting industry: The New York Times characterized the site as being "read religiously by network presidents, media executives, producers and publicists... because it provides a quick snapshot of the industry on any given day." Brian Williams, then anchor of NBC Nightly News, described the blog as "the closest thing to the bible of what's going on in [the news broadcasting] industry." CNN's Miles O'Brien felt that the site "makes me feel like I'm in the middle of a cocktail party of all people who know what's going on in my business." Both MSNBC's Dan Abrams and CNN's Jeff Greenfield have lauded the site for being good at separating fact from fiction.
