Advertising Campaign By Nadav Kander

The share of advertising spending relative to GDP has changed little across large changes in media. For example, in the US in 1925, the main advertising media were newspapers, magazines, signs on streetcars, and outdoor posters. Advertising spending as a share of GDP was about 2.9 percent. By 1998, television and radio had become major advertising media. Nonetheless, advertising spending as a share of GDP was slightly lower—about 2.4 percent.
A recent advertising innovation is "guerrilla marketing", which involve unusual approaches such as staged encounters in public places, giveaways of products such as cars that are covered with brand messages, and interactive advertising where the viewer can respond to become part of the advertising message.Guerrilla advertising is becoming increasing more popular with a lot of companies. This type of advertising is unpredictable and innovative, which causes consumers to buy the product or idea. This reflects an increasing trend of interactive and "embedded" ads, such as via product placement, having consumers vote through text messages, and various innovations utilizing social network services such as Facebook.
