When has Google shut down a paid service that was popular and under heavy development like GCE and GAE?

They may have, I admit, but I can't think of any. The point is raising the standard Google Reader/Google Buzz/etc. free examples isn't really apropos.

It doesn't have to be as dramatic as a complete shutdown. I bought into Google Apps for Business on the implicit promise it could one day completely replace desktop office apps.

All serious development has slowed down to a crawl. New developments are mostly cosmetic. Bugs never get fixed. Microsoft, miles behind not so long ago is now streets ahead with Office 365, and Google has quite clearly stopped giving a crap.

Google has never shown any interest in the long term pursuit of any product or service that couldn't be sufficiently exploited for advertising, directly or indirectly (collecting data to sell to advertisers), paid or unpaid.

As far as I know, never. I've been compiling a list of live and shut down services/products/etc (~299 so far), and while payment doesn't seem to be an important factor (plenty of shut down paid things, including many more advertising services than I expected), I cannot name a service which was under heavy development and was shut down during said development. However, I think that is just because development tends to stop before the final death knell. Reader, for example, used to regularly update and improve during its heyday.

This sounds very interesting -- is it public or can you make it public?

[gwern]

It's not public yet; I haven't finished it (I need to code 4 variables for like 100 entries, since I only thought of the variables partway through assembling the list, and I have 3 or 4 pages to check for additional entries) and the analysis (logistic regression on the variables, and survival curves).

The idea is to try to predict future shut downs, but it's turned out to be a lot more work than I expected...

They don't have to shut it down. They can raise price dramatically, like the Map API price hike, to drive people off. The thing is we don't know whether the current price is viable for Google or not, or whether it will stay viable tomorrow. It's just there are too many of these instances that people have lost trust. Once trust is lost, it's very difficult to earn it back.

I suppose it wasn't very popular, or under heavy development, but I used Google Translate, and also was impacted when AppEngine went through the crazy price hikes.

Google Answers is the only service I can think off. I don't think it was popular though.

It has to do with margins and focus. Companies time and time again sell /shut down profitable divisions, simply because they're not performing "good enough," whatever that may mean. Google essentially has no competition in advertising so anything else is a joke compared to that. Who knows?
