I believe the following are the major differences between the Developer Subscriptions that have been available for years and the Business Developer Subscriptions that are new.

Developer Subscription
- Intended for one person
- Up to 16 instances, physical or virtual but not cloud-based
- Production use is permitted

Business Developer Subscription
- Intended for a corporate environment
- Up to 25 instances (physical, virtual, or cloud-based)
- Production use not permitted

I think the following are the main differences in the subscriptions.

Developer Subscription

• Intended for one person
• Up to 16 instances, physical or virtual but not cloud-based
• Production use is permitted

Business Developers

• Intended for a corporate environment
• Up to 25 instances (physical, virtual, or cloud-based)
• Production use not permitted

Since the early 1920s amateur radio operators (or "hams") ... have taken advantage of skywave for long-distance (or "DX") communication.

The article is rewriting history by using the term personal computer. Small computers such as that were usually called microcomputers and minicomputers, not personal computers. The article is misleading when it says they were mostly used by hobbyists and mainly for gaming. The article implies that accounting software was never written for them but if I were to take time to do research I am confident I can find examples of accounting software for them. Also, see the Wikipedia article about the PDP-8 minicomputers. It says the PDP-8 was "the first commercially successful minicomputer" and "was introduced on 22 March 1965 priced at $18,500". There were other models that cost less. PDP-8 minicomputers were definitely used by businesses. The article "Memories of a PDP-8 Wrangler" in the "Enter The Business Office" section describes the use of a PDP-8 for accounting purposes. The article is at: https://www.pdp8online.com/mem...

I am more concerned with the abundant use of apostrophes (single quotes) where quotes (double quotes) should be used. Second to that is the superfluous use of commas.
