Analytics / The industry ledger

The industry ledger

Every dated fact behind the news — acquisitions, contracts, certifications, first flights, appointments — one stream, cut any way you need: by theme, country, sector, program or date. A filtered view is a URL: bookmark it and it becomes your standing query.

The industry ledger is an Analytics feature

Ask questions the news pages can’t answer — every acquisition touching one country this year, every certification in a sector, every appointment on a program’s suppliers — each answer sourced, dated and linked. A worked example runs below.
