The curtain has come down on Bruce Rosenblum’s quarter-century on the Warner Bros. lot.

The longtime Warner Bros. TV Group topper bid farewell to the studio’s TV staffers with a heartfelt memo that expresses gratitude to former WB chairman-CEO Barry Meyer but makes no mention of his successor, Kevin Tsujihara.

Rosenblum’s final bow comes two days after WB unveiled a management overhaul of its  TV and home entertainment operations. His exit had been expected ever since Tsujihara prevailed in the race to succeed Meyer in the top job at the studio.

There’s still no word on Rosenblum’s immediate plans. He will retain a high public profile in the next few months in his role as the elected chairman-CEO of the Academy of Television Arts & Sciences.

Here’s Rosenblum’s memo:

Dear Warner Bros. Television Group Colleagues,

It is with a heavy heart that I write to let you know that, following several months of uncertainty, my 26-year run at Warner Bros. has come to an end.

I have had the pleasure of working alongside the most talented, creative and innovative people in our business … from our executives and staff to the amazing group of creative talent both in front of and behind the cameras.  Each of your contributions helped Warner Bros. set the standard for excellence in the television industry.  The magnitude of what you have accomplished has been and continues to be a truly meaningful contribution to Warner Bros.’ overall success and a matter of great pride to myself.

But, for all of our success, what I will take with me are the memories of our team, our culture, and the exceptional creative storytelling that we helped, in some small part, share with the world.   I will also take with me all of the relationships and friendships I’ve enjoyed at our great company.

I was fortunate and honored to spend the past 26 years at Warner Bros.  I was especially fortunate to have Barry as my mentor and friend for my entire time here at the studio … I want to thank him for everything he did for my family, our company and me during his tenure as chairman and CEO.

I look forward to my future adventures and I am encouraged in knowing that wherever they may be, they will ultimately allow me to cross paths with many of you again.

I truly wish each and every one of you the best in the years ahead.  I encourage you to embrace the opportunity to build upon our company’s legacy of television success.

As you can imagine, this is not an easy departure for me, but one that is right for the company, and ultimately my family and me.

With great appreciation, admiration and respect,
