In the 70's and 80's, most larger companies made three "styles" of road bikes. Hard core racing bikes, with the top tube as long as the seat tube. Sport touring bikes, with a top tube slightly shorter than the seat tube. And, recreational/commuting bikes with the top tube notably shorter than the seat tube.

Today, the trend is for even entry level road bikes to be a "pretend" race bike, and use geometry similar to that on bikes used by pro cyclist. This is a nutty as selling people SUV's that are replica's of Indy race cars, but that's what the industry is pushing.
