The document discusses the evolution of web applications from distributed applications to single page applications (SPAs). Distributed applications provided richer interactive experiences but were difficult to update across users, while early web applications updated easily but offered limited features. Browsers and HTML matured to allow creating rich applications solely with client-side technologies like JavaScript, avoiding plugins. This led to single page applications accessed via the browser.

- 3. The major differentiating factor for these two applications was that the distributed applications provided an interactive user experience whereas web applications provided very limited features (due to technology limitations). The downside of distributed applications was that it was very difficult to roll-out and ensure the application updated across all users. Web applications had no such problems because once the application is updated on the server, all users got the updated applications. Both these approaches had pros and cons and something needed to be done to get the best of both worlds. Then came the time when browsers became more capable and HTML became more mature. Creating a rich internet application became possible only using browser based client side technologies. This led developers to write client side code using HTML and JavaScript to create rich internet applications. No need for plugins like Flash and Silverlight. These are better know today as (Single Page Applications or SPAs)
