As AT&T started to make serious changes to the erstwhile Time Warner Inc. a little over two years ago, a question lingered in the media-entertainment industry: Could what has become the most prestigious brand in television, HBO -- which survived the transition from modern-era architect Chris Albrecht to Richard Plepler a decade earlier -- continue its run of success under new management? And not just any new management, AT&T management. 

Well, judging by HBO's burgeoning subscriber count -- nearly 74 million as of last quarterly report -- and its steady slew of recent water-cooler hits, you'd have to say the Jason Kilar Administration carried the HBO baton just fine. 

But one need only examine the subject of HBO's most recent hit, Winning Times, to understand that an organization can't stay successful forever. Yes, Next TV is grieving over the culmination of the Los Angeles Lakers' most embarrassing season ever ... and wondering if Warner Bros. Discovery CEO David Zaslav will be the next Rob Pelinka, president of basketball operations for the Lakers and architect of their current roster. Fair question -- The Sopranos ain't Shark Week. 

In any event, following CEO Kilar's long expected announcement Tuesday that he'll indeed leave WarnerMedia upon closure of the $43 billion spinoff of the media division and merger with Discovery, now expected to happen as soon as the end of this week, WarnerMedia has confirmed the following list of other top-level executives also ankling. (Note the list below was sent by WarnerMedia press reps to Re/code's Peter Kafka, who tweeted it out.)

These folks leave while operating at a high level. And judging by their social media posts, which include a loving goodbye from CRO Tony Goncalvez on LinkedIn posted Wednesday afternoon, they all seem to humbly understand the rich legacy of the media company they depart. 

We now wait to see if Zaslav's team can carry on this legacy from them:

AT&T’s somewhat recently acquired WarnerMedia division has undergone its latest major restructuring, this one to establish new CEO Jason Kilar’s imprint on the media division.

Bob Greenblatt, chairman of WarnerMedia Entertainment and Direct-to-Consumer, and Kevin Reilly, chief content officer of HBO Max, TNT, TBS and trueTV, will be leaving the company. Also exiting is longtime corporate PR man Keith Cocozza, executive VP of corporate marketing and communications.

Expanding her purview will be Warner Bros. Chair and CEO Ann Sarnoff, who will now lead WarnerMedia's newly created Studios and Networks Group. Sarnoff will add HBO, HBO Max, TNT, TBS and TruTV to her existing job portfolio. Also, Casey Bloys, president of HBO Programming, will now also oversee original content for HBO Max and the domestic linear networks TNT, TBS, and TruTV.

Greenblatt, formerly the top entertainment executive at Showtime and NBC, joined WarnerMedia as recently as March 2019, representing AT&T's biggest media executive hire since it closed on the erstwhile Time Warner Inc. just months prior.

Veteran programming executive Reilly had three years remaining on this contract. But speculation about his fate was swirling after it was revealed that he had met with NBCUniversal CEO Jeff Shell. NBCU announced its own restructuring Thursday.

AT&T's newly appointed CEO, John Stankey, announced the appointment of former Hulu boss Kilar as WarnerMedia's top executive on April 1, less than two months before the conglomerate's ambitious launch of HBO Max.

As for HBO Max, AT&T said during its Q2 earnings call that the service had signed up 4.1 million users in its first month, putting it on pace to reach the 50 million U.S. customers AT&T had projected for the platform in its first five years.

But from a pandemic that curtailed HBO Max's lofty original series ambitions, to distribution impasses that kept the HBO Max app off the two biggest connected TV platforms, Roku and Amazon Fire TV, the launch has hardly been as "flawless" as Stankey described during that earnings call.

In a note to staff Friday intercepted by numerous Hollywood trades, Kilar listed the reasons for the restructuring, putting "elevating HBO Max in the organization and expanding its scope globally" at the top.

Here's Kilar's entire memo:

Team-

It has been a little over 90 days since I joined the mission and the team. These past three months have exceeded my already high expectations. As I shared with you recently, my bullishness about our future has only grown as I have gotten to know you much better and as I have gotten to know our company much better. As some of you may recall, I shared three thoughts with you on my first day email:

That history was filled with examples of special entrepreneurial companies that leaned into moments of great change in order to better serve customers.

That our taking smart and bold risks is so important to the road ahead. And,

My belief that missionary companies ultimately shine…and my strong belief that ours is a team filled with missionaries.

With the above as context, I’d like to share some decisions I am announcing today that represent our leaning into this great moment of change, in order to better serve our customers. These changes, which are neither timid nor without risk, are possible in part because we are missionaries that ultimately believe we can and will change the world through story. That is what this all comes back to.

Because of the gift that is the internet, we have what I believe is one of the greatest opportunities in the history of media, which is to deliver our beloved stories and experiences directly to hundreds of millions of consumers across the globe. Earning this ambitious future won’t come easy. To do so, I believe it is vital that we change how we are organized, that we simplify, and that we act boldly and with urgency. The pandemic’s economic pressures and acceleration of direct-to-consumer streaming adoption places an even higher premium on these points.

To accomplish this, we are going to do the following:

We are elevating HBO Max in the organization and expanding its scope globally.

We are simplifying how we organize our studios.

We are creating a consolidated International unit focused on scale and efficiency.

We are bringing our key commercial activities into one group to allow us to operate more strategically.

We are making other structural changes that will help us operate more effectively and efficiently.

Andy Forssell, General Manager of HBO Max, will now be leading a newly created HBO Max operating business unit and report to me. Andy and his team will be responsible for the product, marketing, consumer engagement and global rollout of HBO Max.

Ann Sarnoff, Warner Bros. Chair and CEO, will be leading our newly created Studios and Networks Group, combining original production (content studios) and programming capabilities currently spread across Warner Bros., HBO, HBO Max, TNT, TBS and TruTV. This group will oversee all WarnerMedia television series and motion picture development, production and programming, partnering with Andy to ensure HBO Max is successful globally.

Casey Bloys, President HBO Programming, will also be taking on original content responsibilities for HBO Max and the domestic linear networks TNT, TBS, and TruTV. Casey will report to Ann. Casey and the HBO team have done an incredible job over the last several decades delighting consumers with HBO original programming and I am excited for Casey and this expanded team to have an even greater impact on the world.

The Warner Bros. Motion Pictures Group continues to be led by Chairman Toby Emmerich. Warner Bros. Television Studios group continues to be led by Chairman Peter Roth. Warner Bros. Interactive remains part of the Studios and Networks group, along with our Global Brands and Franchises team including DC led by Pam Lifford, and our Kids, Young Adults and Classics business led by Tom Ascheim, all focused on engaging fans with our brands and franchises through games and other interactive experiences.

Gerhard Zeiler, currently Chief Revenue Officer, will now be leading a newly integrated international group comprised of the international operations of Warner Bros., HBO and Turner Networks. This group will be responsible for local execution of all WarnerMedia linear businesses, commercial activities, and regional programming for HBO Max.

Tony Goncalves, CEO of Otter and a key leader of HBO Max, will lead the new commercial unit that combines the U.S. advertising sales and distribution groups with our home entertainment and content licensing so that all commercial activities are strategically managed across internal and external customers.

Christy Haubegger, Chief Enterprise Inclusion Officer, will now also oversee the global marketing and communications team including branding and corporate social responsibility, as we bring together all of our efforts around equity and inclusion throughout our business.

Jeff Zucker continues as Chairman of WarnerMedia News and Sports. Pascal Desroches (CFO), Rich Tom (CTO), Jim Cummings (CHRO), Priya Dogra (EVP, Strategy and Corporate Development) and Jim Meza (EVP, General Counsel) continue to report to me.

Simplifying our approach and narrowing our focus goes beyond, for example, having one content organization vs two. It also means that we will be reducing the size of our teams, our layers, and our overall workforce. These reductions are not in any way a reflection of the quality of the people impacted nor their work. It is simply a function of the above changes I believe are necessary for WarnerMedia and our collective ability to best serve customers. This is the part that is painful and very hard. It is difficult to find the appropriate words here to say other than that I am very sorry. These are talented, admired leaders and beloved colleagues.

Three of those talented, admired leaders who will be leaving the company are Bob Greenblatt, Kevin Reilly and Keith Cocozza. I want to thank Bob and Kevin for getting us to this point with the integration of HBO and the legacy Turner Networks and launch of HBO Max. It has been such an impressive sequence of events, and we are so much better for it. I also owe a tremendous amount of gratitude and thanks to Keith, for not only helping me navigate these last few months at the company – and with the media – but more importantly for his 19 years at the company through its evolution. I have never met a kinder, more collaborative executive in my career. I can’t wait to see how each of these leaders change the world in the years to come.

I realize this is a lot to take in. And none of us should expect the above changes to be easy. That said, we are successfully navigating a pandemic together and I know that, however challenging the above changes may be, we will also successfully navigate them as well. As each of you take some time to digest the above, I hope that you become more and more energized by how, together, we are boldly leaning into the future and this historic opportunity that is right in front of us. It is an honor to be on this team with each of you.

Three months after former Warner Bros. chief Kevin Tsujihara stepped down from that position amid a sexual harassment scandal, parent AT&T has named BBC Studios Americas president Ann Sarnoff as chair and CEO of the unit.

Sarnoff brings more than 30 years of diverse business and media experience to the role -- from Viacom to the WNBA to Dow Jones and the BBC.

“I am delighted Ann is joining the WarnerMedia team and excited to work side by side with such a talented and accomplished individual. She brings a consistent and proven track record of innovation, creativity and business results to lead an incredibly successful studio to its next chapter of growth,” WarnerMedia CEO John Stankey said in a press release. “Ann has shown the ability to innovate and grow revenues and has embraced the evolution taking place in our industry. I am confident she will be a great cultural fit for WarnerMedia and that our employees will embrace her leadership, enthusiasm and passion for our business.”

Sarnoff will be based in Los Angeles and will officially take the helm of the company later this summer, WarnerMedia said in a press release.

Tsujihara, who had led Warner Bros. for years, stepped down in March,  shortly after he was named to head an expanded unit under its new ownership when published reports said the studio chief lobbied casting directors and other personnel to find roles for an actress with which he was having an affair. Warner Bros was run by a trio of executives in the interim -- Warner Bros. Pictures Group chairman Toby Emmerich; Warner Bros. Television Group president and chief content officer PeterRoth and Warner Bros. EVP and chief financial officer Kim Williams.

“It is a privilege to join a studio with such a storied history,” Sarnoff said in a press release. “Warner Bros. has been an industry leader for decades and is known for creating many of the most iconic film, television and gaming properties. I accept this position excited by the opportunity to work with the most accomplished executives and teams in media, and confident about carrying this incredible heritage forward with them.”

As President of BBC Studios Americas, Sarnoff has been responsible for the company’s diversified business  in the U.S., Canada and Latin America. She oversaw L.A. Productions, linear and digital program sales and co-productions, home entertainment, and licensing. She also led efforts to amplify BBC Studios’ global brands Doctor Who, Top Gear, and the natural history brand BBC Earth. As Board Chair of BritBox Sarnoff has guided the development and growth of the direct-to-consumer service which offersU.S. and Canadian customers the largest collection of British television programming.

“Ann’s contribution to BBC Studios has been immense,” said BBC Studios CEO Tim Davie in a press release. “She has grown our core business as well as driving significant innovation, including the successful creation of BritBox, the growth of BBC America alongside our partner AMCN, the launch of new channels like BBC Earth in Canada, and major new content and production deals. We will miss her generosity and her spirit of collaboration, and we wish her great success at Warner Bros.”

Herb Scannell will step down as president of BBC Worldwide North America this summer, the company said Thursday (May 21).

Scannell, who has been with the company since 2010, will be succeeded by Ann Sarnoff (currently COO) beginning Aug. 1. Scannell will remain with the company throughout the summer to help with the transition.

“After five years, and with a strong leadership team in place, it feels like the right time for me to return to the entrepreneurial path I was on in digital media before I joined BBC Worldwide,” Scannell said.  “The company has a bright future, in no small measure because of the extraordinary talent and leadership of Ann Sarnoff.  I have worked side-by-side with Ann for over 10 years – both here and at Viacom – and it’s been one of the most fruitful partnerships of my career."

While at the helm of BBC Worldwide North America, Scannell has presided over a 50% increase in overall revenue and was instrumental in the growth of BBC-America, including last year's joint venture between BBC Worldwide and AMC Networks, which resulted in AMC taking a 49.9% stake in BBCA and co-investing in future BBC productions.
