Only a few decades ago, the position of Chief Technology Officer didn't even exist. Now, it has become one of the highest and most influential positions in business. Here's your chance to learn from the top CTOs and leading companies, because we've compiled a list of the most influential voices on Twitter who are Chief Technology Officers.

Why this list? Well, it's based on Twitter data culled according to content, follower/following ratios, frequency of tweets, blog popularity, the opinions of other analytics experts and our own subjective judgment.

One note: Some influential voices are not included, either because they don't have active Twitter accounts, or they only tweet about their roles as CTOs sporadically. Here, our goal is to provide the best possible stream of news and insight on the subject of Chief Technology Officers.
