FWIW, I think telephone company billing records have been doing this for nearly a century. Sure, it wasn't the official government policy, but the data was recorded.

"only" ... aware of US call history data being available dating to the 1980s, through the "Hemisphere" programme: https://www.eff.org/cases/hemisphere https://www.eff.org/cases/hemisphere There may well be earlier extant data. It was probably tabulated either on punch-card or magnetic tape, and certainly was used for billing purposes. Prior to the 1980s, large-scale data preservation was quite expensive. If anyone has information of earlier comprehensive call history data surviving to the present, I'd appreciate being illuminated.
