Problem: To improve the efficiency of the lamp, the filament usually consists of multiple coils of coiled fine wire, also known as a 'coiled coil'. For a 60-watt 120-volt lamp, the uncoiled length of the tungsten filament is usually 22.8 inches (580 mm), and the filament diameter is 0.0018 inches (0.046 mm). The advantage of the coiled coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter equal to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface area and light-emitting power. As a result, the filament can then run hotter, which results in a more efficient light source, while reducing the evaporation so that the filament will last longer than a straight filament at the same temperature.
What are the disadvantage of the coiled coil vs a straight filament?

Problem: In 1603, James VI, King of Scots, ascended (as James I) to the English throne and in 1604 negotiated the Treaty of London, ending hostilities with Spain. Now at peace with its main rival, English attention shifted from preying on other nations' colonial infrastructures to the business of establishing its own overseas colonies. The British Empire began to take shape during the early 17th century, with the English settlement of North America and the smaller islands of the Caribbean, and the establishment of private companies, most notably the English East India Company, to administer colonies and overseas trade. This period, until the loss of the Thirteen Colonies after the American War of Independence towards the end of the 18th century, has subsequently been referred to by some historians as the "First British Empire".

Problem: TCM's library of films spans several decades of cinema and includes thousands of film titles. Besides its deals to broadcast film releases from Metro-Goldwyn-Mayer and Warner Bros. Entertainment, Turner Classic Movies also maintains movie licensing rights agreements with Universal Studios, Paramount Pictures, 20th Century Fox, Walt Disney Studios (primarily film content from Walt Disney Pictures, as well as most of the Selznick International Pictures library), Sony Pictures Entertainment (primarily film content from Columbia Pictures), StudioCanal, and Janus Films.
