Horror writer Stephen King used the pseudonym Richard Bachman because his publishers weren't keen to saturate the market with his novels. Mr King writes 365 days a year, so he used his alter-ego to get his material into the market place. Because Richard Bachman was 'unknown', the books sold moderately, but the publishers soon realised they were missing out, and re-published them under a 'Stephen King writing as Richard Bachman' campaign, and they shot to the top of the best seller list. King even incorporated his 'second self' into the plot of one of his novels. Check out everything he's written - it's all wonderful.
