A lot of bloggers will start on WordPress.com (not self-hosted) or Blogger aka BlogSpot aka Google owns your stuff and it can go away any minute and you may never get it back!
Seriously. I have seen it happen too many times to great bloggers who lost everything.
Own your content and be in control of who owns what (and what you can do with it).
There are other popular hosts that bloggers use which are popular due to cost (see below.) BUT… I would NOT recommend these for a long-term solution as TYPICALLY when your site begins to grow they “throttle your site” which will mean downtime. Several of these hosting companies are owned by EIG, which is notorious for doing this, offering poor customer service, outdated equipment and software, and more.
If you are looking to save money, then you may want to consider one of the hosts below but once you start growing you should move after your first year to avoid problems.
Another note to make you aware of, you may read that these guys ROCK because of so many awesome reviews but most affiliates say this because of the higher payouts over other hosts which may be better.
