I feel like the Bloomberg magazine is just a way to reinforce their status as the top disseminator of financial news, so that financial firms don't really think of the other options when looking for new data/terminal subscriptions, because Bloomberg is always "there".
Strange model. It's kind of like, a pretty high quality product you get for free, paid for by the people who purchase the really-really-expensive product.
That faded with the advent of mass-market advertising, which grew tremendously from about 1860 onward, and becoming a mounting concern in the 1890s and 1900s.
I've mentioned Hamilton Holt's short book (notes of a lecture, really), Commercialism and Journalism (1909) a few times. The first section is a very good breakdown of the role of advertising in media.
Crazy, unverified statistic I heard- around 20% of those users only use that subscription for access to their AOL instant messenger clone. All trades are on it, so you've got to be on it too. Walled garden to the extreme.

asset pricing, data, order management, trading platform, STP, risk management are all things you can pay for on top of the terminal itself. some of these services are quite expensive compared to other providers on the street
Its revenues are divided roughly by thirds: advertising, subscribers, and the Economist Intelligence Unit (EIU), a bespoke research consultancy.
"Selling networked computers to banks" wasn't actually as obvious then as you'd think. Wall Street was a relatively boring place and went crazy in the 80s, kind of coinciding with the rise of Bloomberg terminals.
These days, a bloomberg terminal costs $24,000 a year, for a computer and a subscription to Bloomberg's information service, which ostensibly gets high quality and timely market information. It's a good business.
Bloomberg is a really interesting startup story overall.

The system worked well until the 1960s when the volume of trading on busy days overwhelmed the system, sometimes delaying the quotes for hours. There had been plans to build a computer network already, but the data outages made it an urgent issue.
The classic book Business Adventures has a chapter on the chaos sowed by the failure of ticker tape.
