Hello and welcome to the intelligence from The Economist.

Despite the billions of dollars spent researching Alzheimer's, remarkably few drugs have been

developed. But now finally, a range of new treatments is in the pipeline. And every year, music fans and critics battle it out to name which song will be the sound of the summer.

We don't yet know what will triumph this season.

One thing we do know, it's likely to be a very short song.

But first...

Nothing on Fox TV has been quite as exciting as the drama playing out in the Murdoch family.

Media mogul Rupert Murdoch, founder and controlling shareholder of Fox and News Corp is trying to block three of his children from inheriting control of the companies.

This high-stakes move has been rejected in court, but plot twist, an appeal means a new season of entertainment for media watchers. The question is whether the shareholders in these

influential companies are equally invested in the theatrics. Murdox are in the middle of this brutal family

feud for control over the companies, but while all that's going on, the empire that they're

fighting over is actually flourishing. Tom Wainwright is the economist's media editor.

This is surprising for a couple of reasons. One is that succession crises on the whole aren't good for

investors' confidence in companies. And the other is that the two Murdoch-controlled companies

are in industries that investors generally are not very excited about. Linear TV and print journalism,

not the sexiest of industries. And yet the share prices of these two companies have been

rising lately.

So Tom, it is an odd situation, isn't it? You've got legacy media companies, you've got this dysfunctional dynasty. Why is it so popular with investors? It does present a bit of a puzzle.

If we look at the two businesses in turn, start with Fox, which is the bigger of the two.
