Campaign advertising  In politics, campaign advertising is the use of an advertising campaign through the media to influence a political debate, and ultimately, voters. These ads are designed by political consultants and political campaign staff. Many countries restrict the use of broadcast media to broadcast political messaging. In the European Union, many countries do not permit paid-for TV or radio advertising for fear that wealthy groups will gain control of airtime, making fair play impossible and distorting the political debate in the process. In both the United Kingdom and Ireland, paid advertisements are forbidden, though political parties are allowed a small number of party political broadcasts in the run up to election time. The United States has a very free market for broadcast political messaging. Canada allows paid-for political broadcasts but requires equitable access to the airwaves. Campaigns can include several different media (depending on local law). The time span over which political campaign advertising is possible varies greatly from country to country, with campaigns in the United States lasting a year or more to places like the UK and Ireland where advertising is restricted by law to just a short period of weeks before the election. Social media has become very important in political messaging, making it possible to message larger groups of constituents with very little physical effort or expense, but the totality of messaging through these channels is often out of the hands of campaign managers. Political advertising has changed drastically over the last several decades. In his campaign for the 1948 United States presidential election, Harry S. Truman was proud of his accomplishment of shaking approximately 500,000 hands and covering 31,000 miles of ground across the nation. But that accomplishment was soon to pale in comparison when in 1952, the 1952 United States presidential election saw a major change in how candidates reached their potential audiences. With the advent of television, war hero and presidential candidate Dwight D. Eisenhower, created forty twenty-second television spot commercials entitled, "Eisenhower Answers America" where he answered questions from "ordinary" citizens in an attempt to appear accessible to "the common man". These questions were filmed in one day using visitors to Radio City Music Hall, who were filmed gazing up at Eisenhower as he answered questions about the Korean War, government corruption, and the state of the economy. He did not have to shake a half a million hands or travel the country extensively. He won the trust of the American people with his direct approach and subsequently the Presidential election. His vice president was Richard M. Nixon. In the 1960 United States presidential election, Vice President Nixon used a formal television address in his presidential campaign, designed to answer questions about The Cold War and government corruption, and to show Americans that he was the stronger, more experienced candidate.
