Next time you sit down to watch a show in real time - yes people, I quite often watch Location, Location, Location or Grand Designs in real time - spare a thought for what millions of Americans go through each night.
Okay, I know they have digital recording devices in the US too, but in my Los Angeles hotel room the other week I didn't have any skip-the-ads technology, so I was subjected to commercial after commercial.
In a country where the national sport of American football is one long epic feature-length advertisement, the volume of ads on TV really is incredible. And the length of the ad breaks is ludicrous.
Honestly, between ad breaks during, er, Forgetting Sarah Marshall (hey, even though there were 50-or-so channels to choose from, there wasn't anything better to watch) I had time to nip down to reception, borrow their corkscrew (the one in the room was useless), have a quick chat about the new Doctor Who and then get back to the room in time to watch an ad for a company that buys people's old iPhones and see a busty babe and frumpy looking bloke do a cross-promotional push for Forgetting Sarah Marshall actress Kristen Bell's new film. I forget what it was called now.
And, it seems, the cut-throat competition between different TV networks in the US has busted its way into living rooms during ad breaks. Most of the time these rivalries pass viewers by, I'm sure, as they happily pay their cable subscription and watch what the networks dish up to them.
