Effects on ONLINE industries:

Internet marketing has had a large impact on several previously retail-oriented industries including music, film, pharmaceuticals, banking, flea markets, as well as the advertising industry itself. Internet marketing is now overtaking radio marketing in terms of market share.[3] In the music industry, many consumers have been purchasing and downloading music (e.g., MP3 files) over the Internet for several years in addition to purchasing compact discs. By 2008 Apple Inc.'s tunes Store has become the largest music vendor in the United States[4]

The number of banks offering the ability to perform banking tasks online has also increased. Online banking is believed to appeal to customers because it is more convenient than visiting bank branches. Currently over 150 million U.S. adults now bank online, with increasing Internet connection speed being the primary reason for fast growth in the online banking industry.[citation needed] Of those individuals who use the Internet, 44 percent now perform banking activities over the Internet.[citation needed]

Internet auctions have gained popularity. Unique items that could only previously be found at flea markets are being sold on eBay. Specialized e-stores sell items ranging from antiques to movie props. [5][6] As the premier online reselling platform, eBay is often used as a price-basis for specialized items. Buyers and sellers often look at prices on the website before going to flea markets; the price shown on eBay often becomes the item's selling price. It is increasingly common for flea market vendors to place a targeted advertisement on the Internet for each item they are selling online, all while running their business out of their homes.

The effect on the advertising industry itself has been profound. In just a few years, online advertising has grown to be worth tens of billions of dollars annually.[7][8][9] PricewaterhouseCoopers reported that US$16.9 billion was spent on Internet marketing in the U.S. in 2006.[10]

Internet marketing has had a growing impact on the electoral process. In 2008 candidates for President heavily utilized Internet marketing strategies to reach constituents. During the 2007 primaries candidates added on averaged over 500 social network supporters per day to help spread their message.[11] President-elect Barack Obama raised over US$1 million in a single day during his extensive Democratic candidacy campaign, largely due to online donors.[12]
