Context_1 : Emergy is a type of energy (exergy) that is consumed in direct and indirect transformations needed to make a product or service. Emergy is a measure of quality differences between different forms of energy. Emergy is an expression of all the energy used in the work processes that generate a product or service in units of one type of energy. Emergy is measured in units of "emjoule"s, a unit referring to the available energy consumed in transformations. Emergy accounts for different forms of energy and resources (e.g. sunlight, water, fossil fuels, minerals, etc.) Each form is generated by transformation processes in nature and each has a different ability to support work in natural and in human systems. The recognition of these quality differences is a key concept. Context_2 : Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself. The concept can be useful in determining the effectiveness of energy-producing or energy-saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in deciding whether a product contributes to or mitigates global warming. One fundamental purpose for measuring this quantity is to compare the amount of energy produced or saved by the product in question to the amount of energy consumed in producing it. Context_3 : Samsung WatchON, first introduced on Galaxy S4 devices, was a service that allowed users to view programming information on their TV or set-top box, and choose programs directly from their mobile devices. Samsung WatchON also provides real-time programming and VOD content recommendations based on the user's viewing patterns; it also includes a virtual remote controller which uses the built-in IR Blaster of the device to control televisions, home theater systems, and media players of any brand, provided they are IR compatible. Samsung WatchON is available on the Galaxy S4, Galaxy S4 Mini, Galaxy S5, Galaxy S5 Mini, Galaxy Note 3, Galaxy Note 3 Neo, Galaxy Note 4, Galaxy Note Edge, Galaxy Alpha, Galaxy Note 8.0, Galaxy Note 10.1, Galaxy Note 10.1 2014 Edition, Galaxy Note Pro 12.2, Galaxy Tab 2 7.0, Galaxy Tab 2 10.1, Galaxy Tab 3 7.0, Galaxy Tab 3 8.0, Galaxy Tab 3 10.1, Galaxy Tab 4 7.0, Galaxy Tab 4 8.0, Galaxy Tab 4 10.1, Galaxy Tab Pro 8.4, Galaxy Tab Pro 10.1, Galaxy Tab Pro 12.2, Galaxy Tab S 8.4, Galaxy Tab S 10.5, and Gear 2 devices. Context_4 : Tab Energy is marketed as a low calorie energy drink named after Tab, Coca-Cola's original low-calorie cola brand. While it shares the Tab name, it is not a cola product like the original Tab. "Fashion Week Daily" describes it as a “sweet and sour beverage” with a taste “reminiscent of a liquid Jolly Rancher”. It is sweetened with sucralose (rather than saccharin), is pale pink, and lightly carbonated. Context_5 : Mott's is an American company involved primarily in producing apple-based products, particularly juices and sauces. The company was founded in 1842 by Samuel R. Mott in Bouckville, New York, who made apple cider and vinegar. Mott products were exhibited at Philadelphia's Centennial Exposition in 1876 and Chicago's World's Columbian Exposition in 1893. In 1900, the company merged with the W. B. Duffy Cider Company to become Duffy-Mott. In 1933, the company introduced prune juice. Context_6 : William Penn Mott Jr. (October 19, 1909 – September 21, 1992), earned bachelor and master degrees from Michigan State University and University of California, respectively. After graduation, he worked for the San Francisco office of the National Park Service (NPS) as a landscape architect from 1933 to 1940. He then became director of the Oakland, California Zoo. In 1962, he was hired as director od the East Bay Regional Park District until 1967. California Governor Ronald Reagan named Mott as the Director of the California Park Service in 1967, where he remained until 1985, when President Reagan named him to head the U.S. National Park Service (NPS). Mott served at the Federal level until President George W. Bush nominated a replacement for him in 1987. He continued to work for the NPS as a consultant until his death in 1992. His last major project was to transition the Presidio in San Francisco into a national park. Context_7 : The term energy input labeling involved producers of goods and services determining how much energy is used to produce their product, and then including that information on their product packaging. Energy input labeling is sometimes known by the acronym EIL. Energy input labeling provides the advantage of knowing how much energy was used to produce a product, but it does not indicate how much energy a product uses to operate, such as the European Union energy label or the Energy rating label used in Australia and New Zealand, and is not in itself a standard for energy efficiency such as Energy Saving Trust Recommended or Energy Star. Context_8 : The Samsung Galaxy Tab (Stylized as SAMSUNG Galaxy Tab, previously Samsung GALAXY Tab) is a line of upper mid-range Android-based tablet computers produced by Samsung Electronics. It is similar to the Samsung Galaxy Note series except without the Samsung S-Pen stylus. The first model in the series, the 7-inch Samsung Galaxy Tab, was first introduced on 2 September 2010 at the IFA in Berlin. Since then there have been several models released, including models with 7.7, 8.9 and 10.1-inch displays. The Wi-Fi versions of the tablet all include a GPS system whilst the 3G/4G tablets include cellular capability as well. Context_9 : The Samsung Galaxy Tab 7.7 is a tablet computer of a series of Android-based tablet computer produced by Samsung, introduced on 1 September 2011 at IFA in Berlin. Related models are the Galaxy Tab 7.0 Plus, Samsung Galaxy Tab 2 7.0, and Samsung Galaxy Tab 3 7.0. Context_10 : In digital electronics, the power–delay product is a figure of merit correlated with the energy efficiency of a logic gate or logic family. Also known as switching energy, it is the product of power consumption (averaged over a switching event) times the input–output delay, or duration of the switching event. It has the dimension of energy, and measures the energy consumed per switching event. fact_1 : Tab Energy is marketed as a low calorie energy drink named after Tab, Coca-Cola's original low-calorie cola brand. fact_2 :  In 1933, the company introduced prune juice. Question: In 1933, Mott's introduced a product that is consumed in the same manner as Tab Energy. What product was it?
Output: prune juice
