| Abstract: | We use the DATAMATION index of the top 50 domestic IT companies (1975–1995) to track persistence and change at the top of the sector. The trends that we uncover are increasing instability, rejuvenation (declining average age of entrants coupled with increasing average age of quitters), democratization (diminishing revenue inequality at the top) and growing supply‐side intertwining of sub‐sectors and industries within IT due to diversification by long‐term survivors. |
