It’s by Hazeley and Morris. They had John Finnemore on their (excellent) podcast extolling the virtues of The Day Today quite recently.
They are big fans/students of parody and I suppose it’s inevitable that an R4 current affairs spoof by them is going to owe an enormous debt to TDT. But I found it hard to look past in this first episode, despite what I thought were a few very good jokes in there. And a few very obvious nods to comedy fans that they were aware of the debt. For example closing with headlines and including a story about Edmonds on the rampage again.
Yep, they're behind the Ladybird parody books aren't they? (Which I believe they also went into lots of detail and research to get right.)
It's undeniably a very dedicated and affectionate homage, but I agree it's hard to get past looking for similarities and enjoy in its own right - as it's so obvious, it's kind of hard to see the point other than as an extended in-joke.
While we're on the topic, my favourite (real-life, and I assume totally unintentional) OTH homage would be Nick Ferrari's show on LBC radio circa a couple of years ago, some classic lines there. '
A book's just a website made of paper!'
