Who won the Iron Throne? I confess: I don’t know. I missed the Game of Thrones finale Sunday, and then spent all day yesterday avoiding potential spoilers who wanted to talk about it.

But in my book, the throne belongs to AT&T CEO Randall Stephenson, whose company now owns HBO, and all the rest of the Time Warner empire. (Apparently, a replica of the iron throne has been installed at AT&T headquarters in Dallas.) My colleague Geoff Colvin calls Stephenson’s integration task “breathtaking in scale and scope.” I agree. At a time when every company is engaged in transformation, Stephenson’s is “the largest transformation underway at any Fortune 500 company.” He’s taking on Disney, Comcast, Apple, Amazon, Netflix—and, of course, Verizon—all at once. As analyst Craig Moffett puts it, “his goal is nothing less than the complete reinvention of the media ecosystem.”

Can he succeed? Given the checkered history of media mergers, and the sheer ambition of this particular task, you would have to say the odds are about as good as defeating the army of the dead at the Battle of Winterfell. But Stephenson has emerged as one of the most interesting business leaders of our times. He deserves credit in particular for his bold plan to retrain the AT&T work force—a model for the modern tech era. He just might pull it off. And in any event, it will be fun to watch.

You can read Geoff Colvin’s fascinating piece on AT&T, which is in the new edition of Fortune magazine but available online this morning, here. And our 2017 story about Stephenson’s pathbreaking training initiative is here.

New IRS data shows the tax burden is increasingly falling on individuals—corporation tax accounted for just 7.6% of the total take for 2018, which is its lowest share since at least 1960. Individuals paid 57%, and 33% came from employment taxes. Bloomberg

Trump Records

A district judge refused to block the House Democrats' subpoena for President Trump's financial records. Trump's lawyers have a week to appeal the decision. If they fail to stop the subpoena going ahead, Trump's accountants have to hand over the records, allowing Congress to check the president has not violated the emoluments clause of the constitution.

Electric Cars

A survey in the U.K.—carried out by a transport-industry-backed foundation—showed only a quarter of British people would consider buying a fully electric car in the next five years. Why not more? Range is the biggest concern. The U.K. will stop selling conventional fossil-fuel-powered cars and vans by 2040. BBC

Niki Lauda

The three-time F1 champion Niki Lauda has passed away at the age of 70. The Austrian icon barely survived a terrible crash in 1976 at Germany's Nürburgring track, but was back in action six weeks later, before going on to win two more world titles. Lauda was also an aviation entrepreneur, in 1979 setting up an airline called Lauda Air that ended up getting bought by Austrian Airlines. Telegraph
