Which company did Bethesda purchase the Fallout Series from?

Bethesda purchased the Fallout series from Interplay Entertainment because of the financial troubles Interplay was facing at the time. Interplay had been struggling to maintain its financial stability, and as a result, they sold the rights to the Fallout franchise to Bethesda in 2007. This acquisition allowed Bethesda to take over the series and develop subsequent titles, such as Fallout 3, Fallout 4, and Fallout 76, under their own management.
