The VMAs were never second to the Grammys.

It was the AMAs, since they were aired around the same time and had a ratings battle, hence the whole court drama about artists performing at one and not the other.
The VMAs are only coveted to pop culture/MTV/pop fans, but the industry and the rest of general public are for the Grammys. AMAs were very popular at one point; like I said, it went downhill when it changed its air date and fan-voting came about.
