Twitter was the major success story of 2009, garnering headlines, growing at an exponential rate, and winning the adoration of marketers. The Fortune 500 companies were part of that latter group and eagerly hopped aboard the bandwagon, according to a study by the Society for New Communications Research.
In fact, 35 percent of the Fortune 500 companies had active Twitter accounts last year, meaning that they posted at least once every 30 days. Out of the top 100 companies, 47 had Twitter accounts. By contrast, only 22 percent of all Fortune 500 companies have "public-facing corporate blogs," Adweek reports.
Four of the top five corporations -- Wal-Mart, Chevron, ConocoPhillips, and GE -- consistently post on their Twitter accounts, according to the study. Insurance was the industry with the largest Twitter presence, with 13 Fortune 500 insurance companies actively participating in microblogging.
The study shows that major companies are eager to embrace social media to interact with their consumers, but many Fortune 500 companies are passing up other online opportunities, such as SEO. A study earlier this month found that 53 percent of the Fortune 500 had no search visibility for terms related to their businesses.
