At first, to understand better what website hosting service is, we need to look definition of web site hosting. The definition "Website hosting is a service that allows to make websites accessible through Internet, for that web site hosting providers offer to their clients space on the web server and Internet connectivity." So, the web site hosting service elements "server space" and "connection to Internet" are two main areas web hosting companies are working.
History of Web Hosting Services
Certainly "server" has many sophisticated elements like server hardware, operating software, specialised software for running databases, backup systems and security features. Historically web hosting companies are been concentrating only to servers, server software and networking, and didn't provide any content. Let's see how it has been changed lately a little bit.
In early times of building websites, programming and designing of single website was mostly made as custom service, which was really time consuming and cost was very high too. Emergence of free content management systems, like Drupal, Wordpress or Joomla, which are easy to install and offer many design templates in standard packages, made difference how people look to the website building.
Easier Installation of Websites
Some web hosting companies are already made installation of such freeware content management packages easier for their clients and saved installation packages to their server and set up so called "one click installation," which enables their clients install such software packages in simplified manner, with automated database creation (this is one of the hardest part of installation of CMS's).

Since hosting companies are providing more software components for building websites, they also feel more responsibility for getting it work properly for you. The distant future brings closer cooperation between hosting companies and programmers, so your specific questions will be directed to professionals who are able handle them easily, because content management software has become more standardised nowadays.
