It seems that over here in the UK we are being drip fed episodes from the US version of the Who Do You Think You Are?
The next episode featuring Brooke Shields is being shown on BBC One on Sunday 4th July at 9.15pm, three weeks since the previous one.
Is there any logic to the schedules? or should we just blame the World Cup?

In NZ we had the same thing – they definitely weren’t screened in the same order as they were in the US, and we had a one-week break in the middle I think. I suspect that in your case you can probably blame the World Cup though!
