I currently have TWO Britbox accounts (one free courtesy of EE, one I've been paying for before I got the free one), and I am SICK of seeing ads for the service on YouTube with that bloody New Order song. Surely some sort of algorithm should pick up that I already use the service?
I think it actually works the opposite way, where they notice that you have/are interested in BritBox so shows you ads related to it. I got Netflix recently and there is now an abundance of Netflix ads on my YouTube.
