Here's a testimony on John F. Kennedy's sexism and drug use:
"The dark side of the man she calls "the Great Compartmentaliser", and who would identify himself on the telephone as "Michael Carter", was never far away. One day in the swimming pool, he decided that Dave Powers was looking "tense", and coerced Alford into giving the first friend a blow job. "I don't think the president thought I'd do it, but I'm ashamed to say that I did. The president silently watched." With sex, came drugs. Alford claims she was "the guinea pig" for the president's fascination with amyl nitrate – poppers."

Martin Luther King Jr was also a known womanizer.
So I would argue, it isn't that those industries have less flagrant sexual harassment. It's that you just don't hear about it. It doesn't make headlines.
Currently I wonder which side will end up dominating tech culture or if we'll remain at war. Some companies have to send out memos telling people to cut out the sex in the stairwells. Others just don't hire any women and try to make sure they're not discriminating in a way that's illegal (not that hard with "pipeline" arguments, at least for core tech positions). And then others have some balance, and make it work or result in drama like this story.
So, yeah, I have probably over a hundred anecdotes especially in sales but in general saying the right-leaning, ultra-capitalist areas have a lot of it nobody cares to report. Plus, it gets worse in "right to work" (aka fire without cause) states where there's limited job availability or the man/woman being harassed has been at company so long them not getting a reference can be held over them. Lots of reasons not to report.
Look up Kesha. Look up Sony emails. Those are just what leaks.
While tech still has a very long way to go, at least speaking up is becoming acceptable, and won't bar you from the industry for life. An Uber engineer who speaks up will never work for Uber again, but she can still find work in the industry (if she so desires). Someone who speaks up on Wall Street will be "marked" for life and never have the opportunity to work on Wall Street again.
Unlike tech, most professional services (banking/consulting/law), don't require particularly skill, but rather the right pedigree, connections, and social background.
Getting a job in IBD at a bulge bracket means years of striving: the right schools, the right social networks, the right way of "talking", the right "look". The rewards are massive: $100-200-300K bonuses even as a young analyst is the the norm. Loyalty, being able to "eat shit", etc are the traits most admired on the street. Being a "troublemaker" and speaking out against harassment (not even just sexual in nature, but just plain bullying/hazing) earns you the label as "weak" and out of a job. If you've been striving all your life for one of these coveted jobs, you can imagine the immense pressure to grit it out, collect your fat bonus, and drink, snort, and purchase-expensive-toys your stresses away.
Maybe saying something will correct it.
Wall Street is a different animal all together, and in a lot of ways worse. Having lived on both coasts and experienced both types of people (and still working with both types of people) I can tell you first hand that Wall Street is far worse. There is just more easy money to cover stuff up.
Not quite Hollywood, but look e.g. to what's recently happening at Fox News for an industry where that's also pretty extreme...

What is interesting is that there seem to have been a burst of articles in 2016, but nothing in 2017. The first three pages of google results above have almost only articles from 2016, and a few from 2012, 2013, etc.
Maybe sexism sells more when it happens in the tech world, but unfortunately, I think it's happening in every industry , especially where women are a minority.
Banks keep records of all communications and emails. Whatever you said, it is not just stored and available for searching, it is also randomly inspected by annoying regulators and backed up in a bunker for the next 5 years.
Last but not least, they are not populated by 20 years old brogrammers.
Once the West Coast tech world starts paying into the scam you won't hear about sexual transgressions there any more than you do in the world of Wall Street or Hollywood which are, as you hint, 1000x worse. People are just now hearing about guys like Bill Cosby, but his behavior was standard issue.
One thing that does define a difference between SV and at least Wall Street is that fast growth startups tend not to have put proper HR processes in place fast enough, which can create an environment in which harassment is easier.
So this sorta doesn't surprise me.
