Tel T 207 Exam 1 Study Guide Lectures 1 12 Lecture 1 August 27th Basic Telecommunications o Video Games o Telephone o Books o Video TV Movies o Telegraph o Comics o Music o Miscellaneous Telecommunications o Pornography o Social Media Lecture 2 August 29th Basic Business Brief Tips o The Company s Business Model Profits Revenues Costs Does it change over the course of time Does it require complimentary goods Example Xbox console and games o The Competitors Direct vs indirect Degree of substitutability Each competitor will have different strategies o Customers the real battleground Demographics Psychographics Culture attitude style values beliefs etc Previous purchases o The Legal Issues Intellectual property Patents copyrights trademarks trade secrets etc Competition regulation Some markets have to be regulated Torts Privacy publicity product consequences etc o The Cultural Issues Attitudes towards products and competitor s products Cultural integration Cultural consequences Example For Facebook the 55 demographic is growing o The Technological Issues Evolution of product Cost dynamics Functionality and quality Adoption patterns Complimentary products Their evolution Important Definitions o Externality a cost or benefit that results from an activity or transaction and that affects an otherwise uninvolved party who did not choose to incur that cost or benefit o Network effect the effect that one user of a good or service has on the value of that product to other people o Economies of scale the cost advantages that enterprises obtain due to size with cost per unit of output generally decreasing with increasing scale as fixed costs are spread out over more units of output Often operational efficiency is also greater with increasing scale leading to lower variable cost as well Telegraph Business Model o Competitors US postal service was its main competitor o Customers Military Newspapers Banks Businesses o Legal Cultural and Technological Issues Patent There was no interconnectibility Larger telegraph companies started to buy up the smaller ones The telegraph technology was increasing Lecture 3 September 3rd Kronos Effect o Dominant industry player wants to keep dominance o Tries to buy up other technologies to incorporate into their company The Patent o Exclusive rights for a specified period of time to an inventor o Creates incentive for innovation o Gives a reason for other inventors to come about o Prevents others from attempting to freeride on the innovation o Must be non obvious innovation or invention o Must have utility Can t be a trickster device Stages of the Telephone o Stage 1 The Patent Period 1880 1893 o Stage 2 Post Patent 1895 1909 o Stage 3 1909 and on Telephone Business Analysis o The competitors The independents The Postal Service The Radio Cars and Transportation o The customers Bell sold to big areas and cross country lines Independents sold to rural areas Normal families o The Legal Issues Improvement patents Sherman Antitrust Act o Cultural Issues Stronger demand for telephones More people were wanting it o Technological Issues Bell s inventions were being improved Lecture 4 September 5th Radio is not an expensive thing o Amateurs were able to create radios out of miscellaneous things around their house The History of the Radio o Guglielmo Marconi Father of radio o Lee de Forest Audion tube Lecture 5 September 10th Radio Act of 1927 o Created the FRC o Tried to distance the industry from politics Frequency Modulation o FM radio o AM wavelength defined by distance of the start of the point to the start of the next point Info embedded in the height of different waves Had to have the radio fine tuned to get good reception o FM info embedded in the distance between cycles instead of the height Signal to noise ratio highly improved Takes much less power and could be recognized much further Could pack more radio stations into a given range Also figured out a way to send pictures with the same technology This would come into play later on with the first televisions o FCC tried to block FM out of the industry Lecture 6 September 12th THERE IS A POWERPOINT DECK FROM THIS LECTURE THAT RYLAND HAS UPLOADED ONLINE o HE PUT IT THERE DUE TO THE NUMBER OF IMPORTANT AND TECHNICAL TERMS THAT WERE ON IT AND HE WANTED TO MAKE SURE AND COVER THE RADIO INDUSTRY MAKE SURE TO LOOK AT THIS SLIDE DECK AS HE MADE A POINT OF SAYING THAT SOME OF IT WILL BE ON THE MIDTERM AND FINAL Amplitude the maximum extent of a vibration or oscillation measured from the position of equilibrium Wavelength the distance between successive crests of a wave esp points in a sound wave or electromagnetic wave Frequency the rate at which a vibration occurs that constitutes a wave either in a material as in sound waves or in an electromagnetic field as in radio waves and light usually measured per second Cycle a cycle per second one hertz Lecture 7 September 17th ONLY TALKED ABOUT RESEARCH FOR THE PAPER NOT NECESSARY FOR THE MIDTERM Lecture 8 September 19th No one was really behind the tv o RCA NBC and others were against it because they didn t want it to harm the market and industry They also had the FCC in the palm of their hands and didn t want that taken away from them Made a strong argument that tv could share inappropriate videos and harm America o The public wasn t for tv because radio promoted that it was underdeveloped RCA began to create the electronic tv o Farnsworth created the image dissector outside of RCA o RCA didn t own the patent but still used it and waited until Farnsworth sued Farnsworth won the suit in the 1940s Lecture 9 September 24th Copyright o The printing press necessitated copyright o The Bible was the most copied book o Moveable type You could set each page whereas before you had to carve the pages by hand o There were lots of efficiencies to be had Paper type ink etc o Copyright is a claim over information o Stakeholders in copyright Power system Publisher Authors Consumers o Copyright gives a limited monopoly to allow for creativity and invention Pays the creator some money Gives them attribution and protects artists from undue modification of their work o The written word is a technology that everyone had to adopt when the printing press was created No incentive to be literate before the printing press Lecture 10 September 26th Copyright Continued o The original system was a combo of monarchy and publishers control using central registries o John Philip Sousa Believed we would
