In 1975, Ng'weno founded
The Weekly Review, a
journal of political news, commentary and analysis followed in 1977 by
The Nairobi Times, a Sunday
newspaper that later became a daily. At the beginning,
The Weekly Review and
The Nairobi Times being locally owned enterprises, fared well in a field dominated by the (then) foreign owned
Daily Nation and
The Standard but like other local papers, they faced stiff competition from the established papers for little or lack of
advertising from the mostly foreign companies in Kenya. Because the advertising community was still controlled by foreigners, it tended to favour the foreign owned publications. Advertisers were also not too keen to deal with publications that were likely to stir the wrath of the government with inflammatory political reports. Ng'weno's publications lasted an impressive length of time. His publications continued to gain popularity, and
The Weekly Review went on to dominate the weekly news scene for more than 20 years, becoming one of Africa's best
news magazines. Due to diminishing revenue from advertising sales, Ng'weno however, sold
The Nairobi Times in 1983 to
KANU, Kenya's then ruling party. The paper was renamed
The Kenya Times, but its popularity suffered, as it was seen to be the mouthpiece of an oppressive government in a political era likened to dictatorship.
The Kenya Times wound up in July 2010. Ng'weno diversified his media empire, which included other periodicals such as
The Financial Review,
The Industrial Review and
Rainbow, a monthly children's magazine. His publishing company, Stellascope was acquired by KANU when the latter purchased
The Nairobi Times.
The Weekly Review folded on May 17, 1999, after 24 years of publication and Ng'weno moved on to
television broadcasting launching a television station, STV Kenya. Following the sale of STV in 2000, Ng'weno reinvented himself as a historian, drawing on materials from his journalistic career. Jointly with the Nation Media Group he produced the 15-part series, the Making of Nation (2007). Jointly with NTV, he has produced over 160 individual half-hour profiles of important figures in Kenya's history, a series entitled Makers of Nation. ==Personal life==
