In 2000, Morgan was the subject of an investigation after Suzy Jagger wrote a story in The Daily Telegraph revealing that he had bought £20,000 worth of shares in the computer company Viglen soon before the Mirror 's 'City Slickers' column tipped Viglen as a good buy.

In an attempt to cater to a different kind of reader, the Mirror launched the "Mirrorscope" pull-out section on 30 January 1968.
The Press Gazette commented: "The Daily Mirror launched its revolutionary four-page supplement "Mirrorscope".

to be entertaining without being frivolous, and serious without being dull". It was not an immediate success and in 1904 Harmsworth decided to turn it into a pictorial newspaper with a broader focus.
During the Second World War the Mirror positioned itself as the paper of the ordinary soldier and civilian, and was critical of the political leadership and the established parties.
At one stage, the paper was threatened with closure following the publication of a Philip Zec cartoon (captioned by William Connor), which was misinterpreted by Winston Churchill and Herbert Morrison.
Originally pitched to the middle-class reader, it was transformed into a working-class newspaper after 1934, in order to reach a larger audience. It was founded by Alfred Harmsworth, who sold it to his brother Harold Harmsworth (from 1914 Lord Rothermere) in 1913.
In 1963 a restructuring of the media interests of the Harmsworth family led to the Mirror becoming a part of International Publishing Corporation.
