Alastair Aiken, best known as Ali-A, is one of the biggest YouTube personalities hailing from the United Kingdom. He is a well-accomplished gamer whose main claim to fame is the Activision game 'Call of Duty.' He rose to prominence in 2009, when he began to upload his gameplay videos on his YouTube channel ‘Ali-A,’ which has over 18.3 million subscribers. Since then he has made a habit of uploading one or two videos every day. His spectacular talent in video gaming made him an overnight sensation among the videogame addicts and very soon his channel took off and hit the million subscribers mark. Since then he has launched a second YouTube channel called ‘MoreAliA,’ where he has exhibited his considerable talent in video games other than the Call of Duty franchise. He has a huge social following on other social media platforms apart from YouTube as well. Both his Instagram and Twitter accounts have over 2 million followers. Apart from his income through YouTube, he generates a lot of revenue through merchandising, sponsorship, endorsements, and adverts.
