Why Streaming Content Could Be Hollywood’s Final Act
https://www.forbes.com/sites/carolinereid/2024/10/24/why-streaming-could-be-hollywoods-final-act/
The future of Hollywood was reshaped in 1997 with the founding of Netflix, an innovative mail-order DVD rental business by Reed Hastings and Marc Randolph. Unlike traditional rentals, Netflix allowed subscribers to retain DVDs as long as they wanted but required returns before ordering more, allowing the company to collect uninterrupted subscription fees. By 2009, Netflix was shipping nearly a billion DVDs annually but had already set its sights on streaming. The transition to streaming, launched in 2007, faced initial challenges due to limited broadband availability but soon became popular, outpacing the DVD business and bringing Netflix millions of subscribers.
Netflix’s dominance drove traditional media giants to reevaluate their strategies. Disney, initially hesitant, eventually licensed its vast library to Netflix, contributing to the latter’s rise. However, by 2017, Disney pivoted to launch its own platform, Disney+, breaking its Netflix partnership and acquiring 21st Century Fox for content diversification. Disney’s decision sparked a broader industry shift as other studios also developed streaming services, aiming to retain full revenue from direct-to-consumer content instead of sharing it with theaters or traditional networks.
Disney+ quickly gained traction, especially during the pandemic, reaching millions of subscribers and temporarily boosting Disney’s stock. However, the reliance on streaming and subscriber growth strained Disney financially, with high operating costs and content expenses. Content exclusivity backfired, creating complexity for fans, particularly with interconnected Marvel shows, and contributing to user dissatisfaction. Additionally, Disney’s decision to release films like Black Widow simultaneously in theaters and on streaming led to backlash, lawsuits, and lost box office revenue, highlighting the downsides of simultaneous releases.
Facing ballooning expenses and subscriber attrition post-pandemic, Disney’s leadership returned to more traditional revenue models, emphasizing exclusive theater releases and licensing content to third parties. They also introduced cost-saving measures like job cuts and content reductions to stabilize financial losses. This shift echoes a partial return to pre-streaming industry norms as Disney and other studios explore “always-on” channels within their streaming platforms, aiming to balance direct consumer access with sustainable profit models.

Björn Ottosson – OKlch color space
Björn Ottosson proposed OKlch in 2020 to create a color space that can closely mimic how color is perceived by the human eye, predicting perceived lightness, chroma, and hue.
The OK in OKLCH stands for Optimal Color.
- L: Lightness (the perceived brightness of the color)
- C: Chroma (the intensity or saturation of the color)
- H: Hue (the actual color, such as red, blue, green, etc.)

AI and the Law – Copyright Traps for Large Language Models – This new tool can tell you whether AI has stolen your work
https://github.com/computationalprivacy/copyright-traps
Copyright traps (see Meeus et al. (ICML 2024)) are unique, synthetically generated sequences who have been included into the training dataset of CroissantLLM. This dataset allows for the evaluation of Membership Inference Attacks (MIAs) using CroissantLLM as target model, where the goal is to infer whether a certain trap sequence was either included in or excluded from the training data.
This dataset contains non-member (
label=0
) and member (label=1
) trap sequences, which have been generated using this code and by sampling text from LLaMA-2 7B while controlling for sequence length and perplexity. The dataset contains splits according toseq_len_{XX}_n_rep_{YY}
where sequences ofXX={25,50,100}
tokens are considered andYY={10, 100, 1000}
number of repetitions for member sequences. Each dataset also contains the ‘perplexity bucket’ for each trap sequence, where the original paper showed that higher perplexity sequences tend to be more vulnerable.Note that for a fixed sequence length, and across various number of repetitions, each split contains the same set of non-member sequences (
n_rep=0
). Also additional non-members generated in exactly the same way are provided here, which might be required for some MIA methodologies making additional assumptions for the attacker.
