1890 Alfred and Harold launched Comic Cuts, a pictorial magazine aimed at adults who read little or nothing. Together the brothers built up the Amalgamated Press Company, whose profits soon reached £50,000 a year; within five years Answers alone was recording net weekly sales of more than 1 million copies.
1894 He and his brother purchased the Evening News for £25,000; it soon became a valuable property.
1896 The brothers launched the Daily Mail, a daily newspaper for the lower middle-class clerks and office workers travelling daily to the City.
They founded the Daily Mirror that, by 1914, Alfred had turned over to Harold.
