I know in metal it was all 5 strings and a lot of them were Ibanez. Having said that, the 00's was the absolute low point in the history of metal and most of it was just awful.
Pop punk was probably the biggest rock genre and they all used P basses and Stingrays, often painted dayglo pink or green.
Pop music seemed to be mostly electronic so maybe a laptop and keyboard is the way to go.
