Hi Tessa...everything is content now..landscape is changing for the businesses now..if they want to be in front of people they can no longer rely on just ads..writing content enables them to organically reach their ideal customers ..so they hire people with domain knowledge to write content for them..people with traditional qualifications go for journalism and magazine route since they are much harder..writing for businesses is much easier for most people because it just requires basic language skills and a little bit of domain knowledge..so i guess it comes down to individual choices..there are plenty of options out there for all kinds of writing..
