The logo with a blue "R" written backwards with a white star in it is that of Toys R Us and has been in use since 2007. The Toys R Us logo has changed many times over the years. The use of the "R" written backward has been in existence since 1965, but in 1965 to 1970 the Toys R Us logo was black and white, and had no star in it.
