Internet penetration is something I get asked about all the time - specifically as it relates to South Dakota (many people are under the impression that SD just got electricity a few years back, thus, the "world wide internet" is something we only see in picture shows). 

Before diving into an online marketing campaign, good marketers want to know what their reach and frequency will be using the web as a communication vehicle.  eMarketer's daily goodness today was in regards to internet penetration by state in the US.  I've always had difficulty finding good data on this, but the National Telecommunications and Information Administration has a tight little report here that summarizes broadband penetration by state.  The report puts good ole' South Dakota above the likes of Michigan, Missouri, North Carolina, and Iowa in terms of broadband penetration. Yee haw, little doggies!  A business marketing strategy must include a web component, and understanding the technical capabilities of your audience is important to any internet marketing plan.

Here are the highs and lows...props to eMarketer for the charts.
