The guitar is the single most popular instrument in the world. It is played by millions of people in all countries, by all races, of all religions. On top of the millions who play it already, there are probably 10x more who want to learn the guitar, and are seeking beginner guitar lessons.
As with all popular commodities and services, the Internet has tons of guitar lessons for beginners, both free and fee based. Obviously free lessons won't be as high quality nor as structured as the paying tutorials, but that's another story.
The purpose of this post is to answer an interesting question that I get very often, specifically, whether you can learn guitar through online lessons, or not.
