Before being purchased by Jeff Bezos, the Washington Post was part of a conglomerate that also included Kaplan, the test-prep company. As the Post's own profitability declined, the profits from Kaplan kept the conglomerate in the black.

The Post news operation was sold to Bezos, splitting up the conglomerate. I assume the Graham family still owns Kaplan and a few other pieces.

It refers to the Graham Holdings Company which used to own The Washington Post, still owns Slate, and also owns Kaplan.

They also owned a cable company for revenue stability reasons.

Also a reference to the Financial Times, which was owned by Pearson up until the recent sale to Nikkei.
