The Japanese launch was followed in March 1983 by the introduction of CD players and discs to Europe and North America (where CBS Records released sixteen titles). This event is often seen as the "Big Bang" of the digital audio revolution. The new audio disc was enthusiastically received, especially in the early-adopting classical music and audiophile communities, and its handling quality received particular praise. As the price of players gradually came down, and with the introduction of the portable Walkman the CD began to gain popularity in the larger popular and rock music markets. The first artist to sell a million copies on CD was Dire Straits, with their 1985 album Brothers in Arms. The first major artist to have his entire catalogue converted to CD was David Bowie, whose 15 studio albums were made available by RCA Records in February 1985, along with four greatest hits albums. In 1988, 400 million CDs were manufactured by 50 pressing plants around the world.
How many studio albums did David Bowie release in February 1985?

After the death of the replacement bishop Gregory in 345, Constans used his influence to allow Athanasius to return to Alexandria in October 345, amidst the enthusiastic demonstrations of the populace. This began a "golden decade" of peace and prosperity, during which time Athanasius assembled several documents relating to his exiles and returns from exile in the Apology Against the Arians. However, upon Constans's death in 350, another civil war broke out, which left pro-Arian Constantius as sole emperor. An Alexandria local council in 350 replaced (or reaffirmed) Athanasius in his see.
Were the people glad to have him home?

At low frequencies (such as AM broadcast), arrays of vertical towers are used to achieve directionality  and they will occupy large areas of land. For reception, a long Beverage antenna can have significant directivity. For non directional portable use, a short vertical antenna or small loop antenna works well, with the main design challenge being that of impedance matching. With a vertical antenna a loading coil at the base of the antenna may be employed to cancel the reactive component of impedance; small loop antennas are tuned with parallel capacitors for this purpose.
For radio broadcast that one would hear in their car what type of towers are used?
