Utterly wonderful BBC 4 series. Nothing sexy or gimmicky, just people showing us maps and experts talking about them, and then maybe a little modern twist at the end. Proper grown-up TV for people (of any age) who like maps. Wonderful. My top TV of the year so far. I wonder if it will get BAFTA's Huw Wheldon Award. Probably not. Ah well.
The website is also rather good. Find it here.
