Problem: The Sun (United Kingdom):

The Daily Star had been launched in 1978 by Express Newspaper, and by 1981 had begun to affect sales of The Sun. Bingo was introduced as a marketing tool and a 2p drop in cover price removed the Daily Star's competitive advantage opening a new circulation battle which resulted in The Sun neutralising the threat of the new paper. The new editor of The Sun, Kelvin MacKenzie, took up his post in 1981 just after these developments, and "changed the British tabloid concept more profoundly than [Larry] Lamb did", according to Bruce Page, MacKenzie The paper became "more outrageous, opinionated and irreverent than anything ever produced in Britain".

Problem: New Haven, Connecticut:

The American Civil War boosted the local economy with wartime purchases of industrial goods, including that of the New Haven Arms Company, which would later become the Winchester Repeating Arms Company. (Winchester would continue to produce arms in New Haven until 2006, and many of the buildings that were a part of the Winchester plant are now a part of the Winchester Repeating Arms Company Historic District.) After the war, population grew and doubled by the start of the 20th century, most notably due to the influx of immigrants from southern Europe, particularly Italy. Today, roughly half the populations of East Haven, West Haven, and North Haven are Italian-American. Jewish immigration to New Haven has left an enduring mark on the city. Westville was the center of Jewish life in New Haven, though today many have fanned out to suburban communities such as Woodbridge and Cheshire.
