Nintendo Switch took lead on Black Friday

Gamers are enthusiastic about the expectation of PlayStation and Xbox. But the next generation won't be available until next year.

The Nintendo Switch was the most popular item sold on Black Friday, according to analysts who credit their success to a competition gap.

Nintendo offered the exact same deal as last year: The Switch console came with a free download of Mario Kart 8 for $299, which resulted in over a $50 savings.
