deep dive
/diːp daɪv/
Very CommonA thorough investigation or detailed look at something. Both a corporate phrase and an internet content genre.
The corporate and internet uses are distinct in tone. The internet version ('deep dive thread on X') is often genuinely substantive. The corporate version ('let's do a deep dive on Q3') is often just a long meeting.
