Sony Corp. on Thursday renamed itself Sony Group Corp. in the first name change in over six decades, a symbolic change for the conglomerate that encompasses financial services, gaming and entertainment.

The name change represents Sony's diversification of its business from its well-known electronics segment, which rolled out Walkman portable music players and TVs that popularized the "It's a Sony" slogan.

Sony Group will seek to maximize synergies among its group companies and foster growth areas. Sony Electronics Corp. took on the name Sony Corp. from Thursday.
