Advertisers have to go somewhere. They always do. They moved from radio to TV starting in the late 1950s. That didn't kill radio, but it didn't help it. TV advertisers moved to cable. Most advertisers began to consider the Internet a viable medium in the early part of the decade. Last year, online ad revenue topped $23 billion, but it was wounded, up barely 10% from 2007. This year the total will probably be down...
...bringing new Americans and their attendant prosperity to far-off corners of the then-unsettled country. American passenger trains carried millions of new soldiers to their training depots and their ports of call during the two World Wars, and, until the expansion of the interstate highway system in the 1950s, rail travel remained the only reliable and affordable method for traversing the country. But, since then, American passenger rail has steadily declined in both prestige and ridership; in 1971, the federal government effectively bought out the dying industry under the aegis of the taxpayer-backed firm Amtrak...
...Cuba marked a small but significant change in the U.S.'s position toward the island. Obama also agreed to let telecommunications companies - long barred under the embargo - to pursue business in the country, which still has roughly the same number of phone lines as it did in the 1950s. But the fate of the embargo rests in the sensitive hands of politicians, and no one is sure what Cuba's reaction will be. President Raúl Castro (who took over for his brother after Fidel underwent surgery in 2006) has indicated that he would like to open a dialogue...
...especially one like the piñon pine. The hardy evergreen is adapted to life in the hot, parched American Southwest, so it takes more than a little dry spell to affect it. In fact, it requires a once-in-a-century event like the extended drought of the 1950s, which scientists now believe led to widespread tree mortality in the Four Corners area of Utah, Colorado, New Mexico and Arizona...
...around 2002, researchers were surprised to see up to 10% of the piñon pines die off, even though that dry spell was much milder than the one before. The difference in 2002 was the five decades of global warming that had transpired since the drought in the 1950s. That led terrestrial ecologists at the University of Arizona (UA) to pose the question, With temperatures set to rise sharply over the coming century if climate change goes unchecked, what impact will it have on the piñon pine?
