Throughout the year, we publish new Lists on the top companies, executives and deals in the Washington region based on our research. Every week there are new topics explored, new industries to delve into. Most of the time, that research comes from the surveys I conduct year-round of regional companies and organizations. Sometimes we also make Lists based on third-party data, when I find a trusted and reliable source. Along with each List, I also include related stats and stories to expand on the topic, which we call the List Extra.
