To be clear, Peacock was basically a nothing-brand in the UK. It didn't even try. I don't think I saw a single ad for it, and it was just a slightly odd tile in Sky's system. I'm not even sure you could subscribe to it outside of Sky. Show's like "Poker Face" weren't even within that tile - just getting into Sky's main categories.
Last time I checked, and this was *months* ago, there were a sum-total of just 15 series within "Peacock."
Comcast's big brands in the UK are Sky - historically a satellite delivery brand, and the UK's largest pay TV operator (we're much more satellite that wired for cable here) - and Now which is their streaming-only brand.
But while I'm sure Comcast marketing folk could explain to me why they maintain the two brands, there's a vast overlap. You can down subscribe to Sky just using streaming, which means that it mirrors Now. And they both have the same undifferentiated offerings. Maybe Sky historically tied you into longer contracts, whereas Now has month-by-month offerings like most streamers. Peacock's awareness must have been close to zero here.
