We recently released a list of the 50 most powerful companies in America.

To create this list, we factored in fiscal revenue, number of employees, press mentions, and social media influence, as ranked on a scale of 1 to 100 by Klout, a site that analyzes social-media influence of companies and individuals across all platforms.

We decided to re-rank the companies by Klout score to determine which companies command the most influence on social media. Read here for a detailed description of how Klout score is calculated.

Tech giants Amazon and Microsoft are both in the top spot with a near-perfect Klout score of 99 out of a possible 100. Walmart, the No. 1 most powerful company in America, drops to No. 18 when ranked only by social media influence.
