In the 1950s, furniture makers were all but anonymous. Gomme's advertising strategy soon had people asking for G-Plan by name -- something new in this era. In addition, the brand offered coordinated pieces for every room in the home, rather than the traditional idea of "suites". This way, people could buy a piece as they could afford it, rather than all at once. And the "constant range" meant that the furniture was a consistent style for the whole house, and one that did not change over the years as people were purchasing additional pieces.
Finally, the contemporary style of G-Plan was mass marketed to the people. This worked so well, that although people bought traditional furniture in the beginning of the decade, by the end of the '50s, most people bought contemporary.
