YouTube, knowing my interest from the videos I watch, has been serving me ads for something called Peloton (here's the ad - those who know me in real life will appreciate quite how targeted the ad appears to be...). I'd heard of this from my brother, who is an investment banker in London (and who has installed a custom-made, air conditioned, wine cellar in his basement), and who says that lots of his friends are part of it.
The deal is you buy a stationary bicycle from Peloton, and then ride it in your house while watching streamed videos of spin classes and taking part in online social interactions.
So far, so good. Then I looked at the price of the bike and the £39/month subscription, and realised that it's probably aimed at investment bankers with wine cellars rather than the likes of me...
