CHANNEL OVERVIEW: The allure of high-stakes gambling in many forms brought in the viewers last week, writes Stephen Price

At least with Channel 4’s Million Pound Drop the punter has a chance; at RBS the punter was the last thing on the board’s mind as BBC2 exposed the bank’s eye wateringly scandalous hubris and delusion.

On Monday at 9pm, BBC2’s documentary RBS - Inside The Bank That Ran Out Of Money was watched by 1.6million/6%, beating Channel 5’s Charley Boorman: Extreme Frontiers (1 million/4%) but just fell short of C4’s Great British Property Scandal ( 1.7million/7% - 2 million/8% incl+1).

On Tuesday, part two of C4’s mini-season achieved 1.6million/7% (1.9million/8% incl+1), ahead of BBC2’s Money (1.5million/6%) and C5’s CSI:Miami on 1.5million/6% (43k extra on +1).

The best audience for C4’s Million Pound Drop Live 90 minute strip this week was Friday’s 9pm finale with 1.8 million/8% (2 million/9% incl+1). However, it wasn’t enough to beat BBC2’s Gardener’s World Christmas Special (2.1 million/9%) with its diametrically opposing audience, or QI at 10pm (2.1 million/10%).

C4 upped the ante to 15 million ‘credits’ on Sunday night when in a cheeky bit of scheduling, it tried to entice The X Factor fans to switch channels after the big finale with an edition of its new drama strand Black Mirror that took talent shows to nightmarish extremes. From 9.30pm, it scored 1.1million/5% (1.2million/5% incl+1), some way behind last week’s 1.9million/8%, the first in the triptych.
