Pre-Upfront Thoughts on Broadcast TV, Promotions, Nielsen, and AVOD by Steve Sternberg
April 2021 #105 ________________________________________________________________________________________ _______ Pre-Upfront Thoughts on Broadcast TV, Promotions, Nielsen, and AVOD By Steve Sternberg Last year’s upfront season was different from any I’ve been involved in during my 40 years in the business. Because of the COVID-19 pandemic, there were no live network presentations to the industry, and for the first time since I’ve been evaluating television programming, I did not watch any of the fall pilots before the shows aired. Many new and returning series experienced production delays, resulting in staggered premieres, shortened seasons, and unexpected cancellations. The big San Diego and New York comic-cons were canceled. There was virtually no pre-season buzz for new broadcast or cable series. Stuck at home with fewer new episodes of scripted series than ever to watch on ad-supported TV, people turned to streaming services in large numbers. Netflix, which had plenty of shows in the pipeline, surged in terms of both viewers and new subscribers. Disney+, boosted by season 2 of The Mandalorian and new Marvel series, WandaVision and Falcon and the Winter Soldier, was able to experience tremendous growth. A Sternberg Report Sponsored Message The Sternberg Report ©2021 ________________________________________________________________________________________ _______ Amazon Prime Video, and Hulu also managed to substantially grow their subscriber bases. Warner Bros. announcing it would release all of its movies in 2021 simultaneously in theaters and on HBO Max (led by Wonder Woman 1984 and Godzilla vs. Kong), helped add subscribers to that streaming platform as well – as did its successful original series, The Flight Attendant. CBS All Access, rebranded as Paramount+, also enjoyed growth. -

An Investigation Into the Security and Privacy of Ios VPN Applications
An Investigation Into the Security and Privacy of iOS VPN Applications Jack Wilson Division of Cybersecurity School of Design and Informatics Abertay University, Dundee A thesis submitted for the degree of Bachelor of Science with Honours in Ethical Hacking 1st May 2018 Word Count: 11,448 Abstract Due to the increasing number of recommendations for people to use VPN’s for privacy reasons, more app developers are creating VPN apps and publishing them on the Apple App Store and Google Play Store. In this ‘gold rush’, apps are being developed quickly and, in turn, not being developed with security fully in mind. This paper investigated a selection of free VPN applications available on the Apple App Store (for iOS devices) and test the apps for security and privacy. This includes testing for any traffic being transmitted over plain HTTP, DNS leakage and transmission of personally-identifiable information (such as phone number, IMEI 1, email address, MAC address) and evaluating the security of the tunnelling protocol used by the VPN. The testing methodology involved installing free VPN apps on a test device (an iPhone 6 running iOS 11), simulating network traffic for a pre-defined period of time and capturing the traffic (either through ARP spoofing, or through a proxy program such as Burpsuite). This allows for all traffic to be analysed to check for anything being sent without encryption. Other issues that often cause de-anonymisation with VPN applications such as DNS leakage can be tested using websites such as dnsleaktest.com. The research found several common security issues with the VPN applications that were tested, with a large majority of the applications tested failing to implement HTTPS. -

ZOOM is a fast-paced, pop-art inspired, multi-plot contemporary comedy. The film consists of three seemingly separate but ultimately interlinked storylines about a comic book artist, a novelist, and a film director. Each character lives in a separate world but authors a story about the life of another. The comic book artist, Emma, works by day at an artificial love doll factory, and is hoping to undergo a secret cosmetic procedure. Emma’s comic tells the story of Edward, a cocky film director with a debilitating secret about his anatomy. The director, Edward, creates a film that features Michelle, an aspiring novelist who escapes to Brazil and abandons her former life as a model. Michelle, pens a novel that tells the tale of Emma, who works at an artificial love doll factory… And so it goes.. -

Everyone's Guide to Bypassing Internet Censorship
EVERYONE’S GUIDE TO BY-PASSING INTERNET CENSORSHIP FOR CITIZENS WORLDWIDE A CIVISEC PROJECT The Citizen Lab The University of Toronto September, 2007 cover illustration by Jane Gowan Glossary page 4 Introduction page 5 Choosing Circumvention page 8 User self-assessment Provider self-assessment Technology page 17 Web-based Circumvention Systems Tunneling Software Anonymous Communications Systems Tricks of the trade page 28 Things to remember page 29 Further reading page 29 Circumvention Technologies Circumvention technologies are any tools, software, or methods used to bypass Inter- net filtering. These can range from complex computer programs to relatively simple manual steps, such as accessing a banned website stored on a search engine’s cache, instead of trying to access it directly. Circumvention Providers Circumvention providers install software on a computer in a non-filtered location and make connections to this computer available to those who access the Internet from a censored location. Circumvention providers can range from large commercial organi- zations offering circumvention services for a fee to individuals providing circumven- tion services for free. Circumvention Users Circumvention users are individuals who use circumvention technologies to bypass Internet content filtering. 4 Internet censorship, or content filtering, has become a major global problem. Whereas once it was assumed that states could not control Internet communications, according to research by the OpenNet Initiative (http://opennet.net) more than 25 countries now engage in Internet censorship practices. Those with the most pervasive filtering policies have been found to routinely block access to human rights organi- zations, news, blogs, and web services that challenge the status quo or are deemed threatening or undesirable. -
Analoge Radio En TV
Analoge Radio en TV Rapport uitgebracht aan OPTA Definitief Door Stratix Consulting BV Hilversum, juli 2008 Management samenvatting OPTA heeft, in het kader van de marktanalyse, behoefte aan informatie over de rol van analoge RTV-pakketten in de ontwikkeling van de omroepmarkt. OPTA is met name geïnteresseerd in de factoren die van invloed zijn op i) de vraag van eindgebruikers naar analoge RTV-pakketten en ii) het aanbod van analoge RTV-pakketten door kabelexploitanten, om daarmee inzicht te krijgen in de te verwachten ontwikkeling van deze factoren in de komende jaren. Dit rapport geeft antwoorden op vier vragen van OPTA: 1. Welke factoren zijn van invloed op de continuering van doorgifte en/of de omvang van een analoog RTV-pakket dat door kabelexploitanten (en exploitanten van een FttH netwerk) wordt aangeboden? 2. In welke richting ontwikkelen die factoren zich, en welke ontwikkelingen zijn als gevolg daarvan in de komende 3-5 jaar te verwachten op het gebied van doorgifte van analoge RTV-pakketten? 3. Welke rol speelt een analoog RTV-pakket in de komende 3-5 jaar in de RTV-markt? In hoeverre beïnvloedt de (on)mogelijkheid van een analoog RTV-pakket Nederlandse consumenten bij de keuze tussen RTV-dienstverlening via de verschillende RTV- transmissieplatforms (kabel, satelliet, DVB-T, xDSL en FTTH)? Indien nodig moet een nader onderscheid gemaakt worden tussen het belang van analoge radiopakketten en analoge televisiepakketten. 4. Op welke termijn verwacht uw onderzoeksbureau dat het merendeel van consumenten enkel nog digitale RTV-pakketten zal willen gebruiken? Welke aanwijzingen zijn er op dit moment te onderkennen binnen de geïdentificeerde factoren, die van doorslaggevend belang zijn voor het bereiken van die situatie? Op deze vragen zijn de volgende antwoorden gevonden: 1. -

Threat Modeling and Circumvention of Internet Censorship by David Fifield
Threat modeling and circumvention of Internet censorship By David Fifield A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Computer Science in the Graduate Division of the University of California, Berkeley Committee in charge: Professor J.D. Tygar, Chair Professor Deirdre Mulligan Professor Vern Paxson Fall 2017 1 Abstract Threat modeling and circumvention of Internet censorship by David Fifield Doctor of Philosophy in Computer Science University of California, Berkeley Professor J.D. Tygar, Chair Research on Internet censorship is hampered by poor models of censor behavior. Censor models guide the development of circumvention systems, so it is important to get them right. A censor model should be understood not just as a set of capabilities|such as the ability to monitor network traffic—but as a set of priorities constrained by resource limitations. My research addresses the twin themes of modeling and circumvention. With a grounding in empirical research, I build up an abstract model of the circumvention problem and examine how to adapt it to concrete censorship challenges. I describe the results of experiments on censors that probe their strengths and weaknesses; specifically, on the subject of active probing to discover proxy servers, and on delays in their reaction to changes in circumvention. I present two circumvention designs: domain fronting, which derives its resistance to blocking from the censor's reluctance to block other useful services; and Snowflake, based on quickly changing peer-to-peer proxy servers. I hope to change the perception that the circumvention problem is a cat-and-mouse game that affords only incremental and temporary advancements.
