There's a "prime time" for TV, and it's after dinner. There's a "prime time" for radio, and it's when people are driving to or from work. But what about gaming?

Yes, gaming has a prime time as well, according to research done by Nielsen, which indicates that the peak time for playing video games is, unsurprisingly, between 7pm and 11pm.

What is surprising is the few hours before that, when things really start to pick up at around 2pm. Who finishes work or school that early on a weekday?

Oh yeah. College students.
