Scrum Master Trends: What was your job title before becoming a Scrum Master or Agile Coach? ("Line Manager" is missing...)

I found the "Scrum Master Trends" report very interesting. I was looking at the "What was your job title before becoming a Scrum Master or Agile Coach?" question specifically, as during agile transition, the question of "who should become a SM?" is very popular.
