n March 1, 1971, Business Day published a record of the previous year’s highest-grossing Philippine firms. Eight years later, the Securities and Exchange Commission and Business Day launched 1000 Top Corporations in the Philippines gazette. This effort laid the
foundation for what is now known as Business World Top 1000 Corporations in the Philippines

an annual magazine that provides readers with corporate financial data.

Business Day survived the martial law period,[4] partly due to President Ferdinand Marcos
allowing the paper to run because it did not cover politics, a move calculated to give a
veneer of press freedom to his authoritarian regime

After the 1986 People Power Revolution, the paper eventually closed on June 5, 1987, due
 to a labor strike. Employees who did not join the strike quickly regrouped with Losin
 to set up the current Business World Publishing Corporation.
