IGN has laid off an unspecified number of editorial employees today, Polygon has learned, and plans to shutter sites 1up.com, GameSpy.com and UGO.com.

According to an internal memo from Ziff Davis CEO Vivek Shah, "Our goal is to do fewer things and to do them exceptionally well. In that vein, we want to direct all of our energy and work behind our two flagship brands: IGN and AskMen."

Shah writes that Ziff Davis, which recently acquired the IGN network of websites, will be "winding down" 1UP, UGO and GameSpy. 1UP editor-in-chief Jeremy Parish tweeted, "We won't be killing the site today; I'll post more thoughts later. On 1UP!" UGO editor-in-chief Chris Radtke wrote in a goodbye letter to readers, "UGO is dead." While editorial staffers for some of the IGN-owned shuttered sites have been laid off, sources tell Polygon that some personell will be rolled into IGN.com's editorial team.

The company is also looking for a buyer of IPL, IGN's eSports network. Rather than coordinate and publicize its own IGN Pro League, "IGN's role going forward will be to broadcast and cover a variety of eSports events."

Shah's memo can be read below.

Subject: Staff Announcement

Today, we took some difficult but important actions that will ensure the continued growth and health of IGN and AskMen. Before I go into more details about the changes, you should know that they resulted in the elimination of jobs at IGN. It's always upsetting to say goodbye to colleagues and let's do what we can to help these employees as they seek new opportunities.

It's also important for you to know that we are absolutely confident that we now have the best structure and team to successfully move the company forward and that there are no further planned reductions.

The changes we made today are designed to allow us to Simplify and Focus. Our goal is to do fewer things and to do them exceptionally well. In that vein, we want to direct all of our energy and work behind our two flagship brands: IGN and AskMen. They are both category killers and share a vision of a multi-screen (PCs, tablets, smartphones, TV) and multi-format (text, photos and video) world.

As a result of our decision to focus on our core brands, we are:

· Winding down 1UP.com, UGO.com and GameSpy.com;

· No longer ad repping 3rd party sites such as GameStop.com and FamilyGuy.com;

· Actively engaged with parties interested in acquiring IPL. IGN's role going forward will be to broadcast and cover a variety of eSports events;

· Dividing our ad sales team into two: one focused on IGN and the other focused on AskMen.

On the IGN front, Peer Schneider will continue to oversee all of editorial and product, focusing those resources exclusively on IGN. The foundation of this entire company is its content and we will continue to have the best people in the industry producing it.

Charlie Barrett will oversee the monetization of IGN everywhere in the U.S. - PCs, tablets, smartphones, YouTube, consoles - and now be able to concentrate the sales and ad ops teams' efforts where they can make the most impact.

Frank Puma will assume an exciting new role as executive director of programs and solutions, reporting to Charlie. The sales development, design and creative teams will report to Frank, whose charge is to deliver world-class advertising experiences.

A new head of engineering and technology for IGN will be recruited as quickly as possible. Tech has a monumental role to play in the growth of IGN and will be committed to working hand-in-glove with edit, product and sales.

On the AskMen front, Ric Poupada will continue to oversee all aspects of the AskMen organization and is excited to have a new VP of sales, Paul Chenier, reporting to him. Paul has been a longtime advocate of the AskMen brand and is one of the most talented sales executives in our organization. Having him build a dedicated AskMen ad sales team will do wonders for the business.

Ian Chambers will continue to run International out of the UK for both IGN and AskMen and we're thrilled with the performance of our businesses overseas.

Mike Etheridge will be the VP of finance and operations for IGN and AskMen, working across all of the departments to ensure that we're growing our business, expanding our margins and making metric-based decisions.

Rachelle Igoe will be the head of human resources for IGN and AskMen, ensuring that we continue to nurture, attract and retain the best talent in the industry.

I'm sure that there will be a number of questions in the days and weeks ahead but please know that we will be a better functioning and nimbler organization from this moment forward.

As I said on day one, openness and transparency are important, so please email me at [removed] if you have any questions, thoughts or ideas.
