P2P Streaming

P2P streaming is the peer-to-peer video-delivery route that let users watch while downloading and share already-downloaded chunks with other users. In No.204 互联网视频平台混战：从后舍男生到漫长的季节 | 中国互联网故事21, it is one of the two big technical shifts before the mature platform era, alongside Flash browser playback.

The episode uses PPLive, PPS, and early live events to show why P2P mattered: it helped reduce live-streaming bottlenecks before centralized CDN-heavy streaming and app platforms became dominant.

Key Claims

• P2P streaming was an infrastructure workaround for bandwidth scarcity.
• It enabled live and on-demand video before platform economics became mostly about licensed content.
• Its advantage weakened as copyright costs, financing, and large-platform content ecosystems became decisive.

Connections

• PPLive, PPS, and 姚欣 / Yao Xin — major cases in the episode.
• 优酷 / Youku and 土豆网 / Tudou — parallel Flash/web-video platform route.
• Chinese Long-Video Platform Economics — later phase where content costs outweighed P2P technical advantage.
