The results of comparing the job titles associated with professional bet takers yielded interesting results. The term "bookmaker" was the preferred one most of the time, reaching its apex around the 40's; using the term bookie, on the other hand, was not very popular in comparison, and others, such as "betting agent" were used rarely. But after the 40's everything starts to shift. The word bookmaker was appearing less and less in books, reaching its lowest point in 2000 since the 19th century. "Bookie", however, which started gaining popularity in the 1900's, actually surpasses "bookmaker" in 1980 and by 2000 it is a far more popular term to describe the profession than "bookmaker".
Between "self-employed", "small business" and "entrepreneur" the case is clearer and more straightforward. "Entrepreneur" is the most popular, then small business and, by a great gap, self-employed.
