Technology, without any global-scale conflicts, developed a great deal slower than it did in our world.
Radio first appeared in the 1920s, much as it did in our world. It would be the dominant form of entertainment and communication until about 1975.
Television was first invented in the 1940s, but didn't leave the laboratories until about the 1960s, gradually gaining popularity despite its high price. However, by 1990, 66% of people in North America own a television set.
Telephones had been in use to some degree since the 1900s, and rather quickly grew in popularity. Thanks to a government initiative on the part of President Eisenhower in 1955, the entire United States of America had telephone service by 1960; all of Canada and Orb had telephones by the end of the 1960s. By 2000, 80% of the world has telephone access.
The first computers were devised in the mid-1950s. However, due to size and limited power, computers stayed little more than laboratory gimmicks. In the 1980s, however, scientists finally came out with viable systems that various governments and corporations began using for storing records. In the year 2000, IBM announced that small computers for individual use, or, "personal computers" would be available within 20 years.
The first arcade games (a digitized tennis game, a haunted maze, and a first-person shooter) were released in 2009 and became immensely popular in Europe and North America. However, due to fears that they would "corrupt the youth", some more conservative governments sought to have them banned.
Developed largely the same as in our world, except remained popular after the 1980s.
The first Compact Disks (or CD's for short) were developed in the mid-2000s and the first music album ever released to CD (Brian Eno's A Long Journey Across the Moon) came out on April 16, 2011.
Cassette tapes first hit the scene as a means of portable music playback in 1987. By the year 2005, they were the second most popular audio medium, and a close second at that.
Video tapes first hit the market in 1998. By 2013, there were three principal formats: VHS, Beta (by Sony), and ImageTek (by a German company), and each was competing for dominance in something the media dubbed "the tape wars".
AutomobilesCars first became widespread in the 1920s, thanks to the work of Henry Ford. By 1980, 80% of the western world owned a car. In the year 2000, front wheel drive was introduced, reducing slipping in icy weather.
While cars were used for short-distance travel, trains remained the dominant form of long-distance travel. In the 1980s, certain western countries began switching from steam-driven to diesel-fuel-powered locomotives.
The Wright Brothers first flew in 1903. However, airplanes didn't gain much popularity until they were developed to the point that they could fly across the Atlantic (first achieved in 1960). Since then, they have been rapidly gaining popularity. The first jet airplane was introduced in 1999.
Ships developed largely the same as in our world, though aircraft carriers were not invented until the 1970s.
On June 2, 2011, a jet plane whose jet engine had been replaced with a custom-built rocket flew to an altitude of 65 miles.
