Thank you one and all for all the birthday greetings yesterday. Because I now pretty much only watch video content on YouTube, I treated myself to a premium subscription. Maths fans and budding start-ups might be interested to know: number of times you need to be served an advert for Nigel Farage’s daily investment news bulletin before you snap and go premium = 43. Next question: As I get YouTube Music bundled in, do I now cancel my Spotify subscription?
