First compact disc

The standard for the compact disc was first proposed by Philips (Netherlands) and Sony (Japan) in 1980, and agreed upon in 1981 by the Compact Disc Standard Digital Audio Disc Committee. The first CDs became available to the public in Europe and Japan in the autumn of 1982, and the USA in 1983, where 800,000 discs were sold in the first year alone.

First country to ban incandescent light bulbs

The first countries in the world to announce plans to ban incandescent light bulbs (and to then replace them with more energy-efficient fluorescent bulbs) were Cuba and Venezuela (in 2005). Two years later, Australia’s environment minister announced their plan on 20 February 2007. These moves could potentially reduce Australia’s greenhouse gas emissions by 800,000 tonnes by 2009 or 4 million tonnes by 2012.
