I was talking to some smart folks yesterday who used to work at Dunnhumby on the enormous Tesco CRM account. We were chatting about Tesco and I asked them if Tesco stood for anything. I assumed it was would the "something"-Company and was interested what the "something" was. Apparently not. According to them the company was named after Jack Cohen's mum, Tessa.
Reminded me of a story that I heard once about the Weinstein brothers, Bob and Harvey. They named their movie company Miramax after Miriam and Max, their mum and dad. Apparently when the company was in deep financial trouble and the rumour was that they were about to sell, the one thing that they cared about was keeping the Miramax name under their control.
The power of parents.
(BTW, Yahoo Answers disputes the fact that Tesco was named after a Tessa Cohen, but until someone tells me otherwise I am believing it - it makes for a much nicer story)
