Ree Drummond (Pioneer Woman) has also built up a food & cooking empire - blog, tv show, family appearances, store(s), clothing line, B&B hotel, tours - based at her studio-lodge at the Drummond ranch in Oklahoma and in local town Pawhuska. Again, she's sharp and a hard worker. She has a quite a self-deprecating sense of humour which definitely helps to sell the brand, and her husband Ladd (another grafter) is an asset in the scenes he's in. Ree Drummond also has plenty of friends and interests, and loads of Oklahoma relatives on both sides who she seems to genuinely love feeding.
Whether Meghan and Harry can duplicate these programmes and businesses for the US market (presumably their main market?), I really don't know. Can they reproduce a version of the successful elements of the above shows - a strong, likeable couple / family; the main cook being a generous 'feeder'; liberally sprinkled twinkling eyes / self-deprecating humor; hard work, talent and focus?
If they use a different formula for the US, will it work?
