Although the traditional media companies first steps into the digital sphere were fairly clumsy, they have quickly learned from their mistakes and continued to enlarge their Internet presence.
During the last years many of the smaller players in the field of digital media have been driven out of competition by the huge media conglomerates. This mainly is a result of the advantages that the commercial media giants have over their less powerful counterparts:
- As engagement in online activities mostly does not lead to quick profits, investors must be able to take losses, which only powerful companies are able to.
- Traditional media outlets usually have huge stocks of digital programming, which they can easily plug into the Internet at little extra cost.
- To generate audience, the big media conglomerates constantly promote their Websites and other digital media products on their traditional media holdings.
- As possessors of the hottest "brands" commercial media companies often get premier locations from browser software makers, Internet service providers, search engines and portals.
- Having the financial resources at their disposition the big media firms are aggressive investors in start-up Internet media companies.
Commercial media companies have close and long ties to advertisers, which enables them to seize most of these revenues.

The first of the great medieval universities was established in Bologna. At the beginning universities predominantly offered a kind of do-it-yourself publishing service.
Books still had to be copied by hand and were so rare that a copy of a widely desired book qualified for being invited to a university. Holding a lecture equaled to reading a book aloud, like a priest read from the Bible during services. Attending a lecture equaled to copy a lecture word by word, so that you had your own copy of a book, thus enabling you to hold a lecture, too.

41st President of the United States. In 1954, George Bush co-founded and became the president of Zapata Offshore Company. By 1964, he became chairman of the Republican Party of Harris County. That same year, he ran for the U.S. Senate, but was defeated in the Democratic landslide. Bush had better luck in the election of 1966, when he became the first Republican ever to represent Houston in Texas. Presidents Nixon and Ford selected Bush for a series of high-profile appointments: Ambassador to the United Nations in 1971, Chairman of the Republican National Committee in 1973, envoy to China in 1974 and Director of Central Intelligence in 1976. When Jimmy Carter was elected President in 1976, he appointed a new Director and George Bush returned to private life. In 1980, Bush made his own run for the Presidency. George Bush sought the Presidency again in 1988, and won the Republican nomination over a large field of candidates. His election that November was a decisive one, though not the landslide he and Reagan had enjoyed in 1984.

The firm began in Germany in 1835, when Carl Bertelsmann founded a religious print shop and publishing establishment in the Westphalian town of Gütersloh. The house remained family-owned and grew steadily for the next century, gradually adding literature, popular fiction, and theology to its title list. Bertelsmann was shut down by the Nazis in 1943, and its physical plant was virtually destroyed by Allied bombing in 1945. The quick growth of the Bertelsmann empire after World War II was fueled by the establishment of global networks of book clubs (from 1950) and music circles (1958). By 1998 Bertelsmann AG comprised more than 300 companies concentrated on various aspects of media. During fiscal year 1997-98, Bertelsmann earned more than US$15 billion in revenue and employed 58.000 people, of whom 24.000 worked in Germany.
