Selecting a "winner" for each console generation is somewhat of a nonsensical engagement. Before even beginning to assess the merits of your sources of sales figures, release dates, review scores and other such relevant texts, you have to consider exactly what qualities a "winner" would possess. Would it be the largest quantity of widely renowned videogame releases of a high quality? Or that which had increased its library from the previous-generation to the greatest extent? Perhaps the defining merit would be the console manufacturer who had managed to increase their market share by the greatest margin? Or that which pushed the industry into new territory? Or maybe, it's simply the console that sold the most units?
