According to annual analyses of circulation conducted by the Pew Research Center, daily newspaper circulation in the United States peaked in 1984, while Sunday paper circulation continued to rise until 1993. Since that time, the readership of newspapers has been on a steady decline. This coincides approximately with the beginning of home Internet use. The rate of the decline in readership increased greatly in 2004, and continued experience its sharpest declines in recent history. The recent slide continues a decades-long trend and adds to the woes of a mature industry already struggling with layoffs and facing the potential sale of some of its flagships. In addition newsstand sales of magazines fell more than 4 percent, to about 48.7 million copies. Among domestic newsweeklies, "Time" magazine reported the biggest drop. Analysts pointed to the increased use of the Internet, noting that more people in 2006 read the "New York Times" online than on paper. Newspaper readership goes up with education, and education levels are rising. That favorable trend is offset by the choice of people in each age group to read fewer papers.
