There are similarities in excludability, where data can be subject to property rights and intellectual property but can also be available to everyone as club goods.

Ownership vs. Access:
Ownership of data is not as straightforward as with private goods. Controlling data, managing contractual relationships, and establishing rules and regulations for access are more relevant considerations with data.

Health Data Management:
Balancing public interest in accessible health data for analysis and private interests in data control is crucial. No clear solutions exist yet for managing this balance.

Data as Sunshine:
At Google, data is viewed as sunshine, available for everyone. The focus is on sharing rules, requirements, and options for data sharing.

Data’s Impact on Competition:
Data amplifies its value when refined and analyzed. This makes data scientists highly sought after. Data benefits various organizations, including universities, retail chains, and the automotive industry.

Concentration of Power:
The concern that data’s positive feedback loop could lead to extreme outcomes and perpetual power imbalances remains a challenge.

Competition in the Streaming Video Industry:
Improved distribution systems have led to increased competition in the streaming video industry, with players like Netflix, Amazon, Google, and Hulu offering a diverse range of content. The rise of streaming video has resulted in a “golden age of television,” with more creative and globally accessible content produced using technology and analytics.
