Back in the 1950s, I mean. Here's Aviation Week for 24 August 1953:
[Headline on the article is "Big Copters May Replace DC-3s by '59"]
"Only six years away is the prospect of fleets of 30- to 50-passenger helicopter buses competing directly with surface carriers for shorthaul inter-city public transportation.
"That is the outlook projected last week by the Air Transport Assn.'s helicopter committee in a significant report, which fits together today's known copter factors with tomorrow's probabilities."
Presumably their biggest error was underestimating helicopter operating costs by some huge factor-- the report hoped a helicopter would have a "direct flight cost" per mile not exceeding "present twin-engine aircraft" on a 200-mile flight. Article doesn't say what "direct" means. How would a large helicopter compare with a twin-prop aircraft of the same capacity now?
So if they did get costs wrong, why did they have so little idea what they actually cost, in 1953?

There was a high profile crash in NYC (don't remember the date) that certainly didn't help. 'Copter service seems to go in and out of vogue at times, and these days would rarely be an option for except the most well-heeled travelers. I liked some of the VTOL concepts from the past, and sometimes wonder if such a design would be economical with today's technological advances.

I'm no expert in helicopters but I would guess they suck far more fuel (maybe not a concern at the time), and need far more maintenance since you really want to avoid any mechanical difficulty, when a twin engined plane can lose an engine or a propeller or a gearbox without much trouble.

When I was off the coast of Vietnam in the late 60s I got lectured about not flying about for the fun of it in helicopters, and that most deaths in the fleet likely would be helicopter related. This is no longer true, helicopters are much safer, but I suspect that it came at a cost. Bettter engineering, materials, engines, transmissions. Helicopters are far more complicated and difficult to keep safely in the air.

Helicopters also are a lot noisier - and it would add a lot of weight to shield the sound. The two times I have been on helicopters a muff style headset (either plain sound reduction ear muffs or communication set) was required. Talking with your seatmate in a normal conversation was all but impossible. I do not see that most passengers would be interested in that experience.

Remember the partnership CO and DL had with US Helicopter? Flights from EWR & JFK to Bridgeport CT, Wall Street, Manhattan and a few others..partnership ended prior to their merger with UA but it seemed valuable while it lasted, USH now defunct. http://en.wikipedia.org/wiki/US_Helicopter

The basic problem comes from a clash between the human desire for something 'cool', and the costly reality. In concept, helicopters can do some amazing things, and if the cost was low & safety/reliability high, the sky would be filled with them. Unfortunately the reality is that they are complex, expensive, and require a whole lot of maintenance per flight hour. The safety factor has improved greatly over the years, but it'd done so at the expense of... expense. A 7-seat helicopter is several times the cost to buy, operate, and service than an equivalent sized airplane. It can do amazing things that planes can't do, but only if the owners really, really need that job done at the given cost.
One smooth landing is skill. Two in a row is luck. Three in a row and someone is lying.

That would be the New York Airways Boeing-Vertol crash on top of the Pan Am building in 1977.
The original helicopter airlines of the 1950s - New York Airways, Chicago Helicopter Airlines and Los Angeles Airways - all suffered horrific accidents due to catastrophic mechanical failures. But it was the imposible operating economics that did them all in.
Trivia question - what major U.S. airline operated scheduled helicopter service in 1954-55?

Helicopters have their own market, SAR/Medevac, police, military, ENG... and they are complementary to business jets/prop.
But it is true that it is almost impossible to operate on scheduled commercial flights due to its high operating cost.

Your source please ?
Pick the regulatory accident DB of your choice...helicopter frame crashes are far more likely (something like a factor of 10) than airliner crashes. It gets worse if you normalize by RPK because helicopters tend to fly less distance with less people.
As Tom as said, look at practically any database; accident rate (as in accident per flying hours) for GA helicopters is around 10 times worse than for GA fixed wing. Not sure about the commercial figures, guess it's similar.

This has always been a dream of aviation enthusiasts...large passenger helicopters, tilt wings or vtol aircraft operating from downtown to downtown...considering all the arguments about which airport is "more convenient" to this or that city or area, it seems that if it could ever be worked out properly, someone could make a lot of money with the idea. I would think business travellers would consider paying a premium for downtown to downtown city center service, that would save time and offer convenience. I was hoping there might be a commercial version of the V-22 that could carry passengers say from Manhattan to downtown BOS, PHL etc....however the noise issue is an environmental impact many of the futurists failed to take into account.One of many hurdles before such service could be considered....

I don't mean to be too picky, but that crash involved a Sikorsky S61. Another NY S61 suffered a tail rotor failure shortly after lifting off from EWR and crashed between 22L and 22R killing at least 3 people on board. That was ~ 1980.
My very first commercial flight was on a NY B-V 107 from EWR to JFK back in 1966. I have to say, 14 minutes flight time between airports sure beat 1 1/2+ hrs drive time between them, even 46 years ago!

How many due to technical issue ?
Most of the accidents are due to pilot errors like on airplane... And i quoted " safety not as good as fixed wing" not as good as airliners... Fixed wing can be a PA18 or an A380 and the factor souldn't be of 10 !
I haven't run the numbers but, based on past reviews, I'd guess it's about 1/3 mechanical, 2/3 pilot error for helicopters...which is way more mechanical than for fixed wing.

I agree that most are pilot error in either case but that's not helping you...helicopters crash more often in absolute terms and they have more mechanical failures (in both relative and absolute terms), all once your normalize for flight hours. That's still true even if you expand from "airliners" to "fixed wings". It may not be a factor of 10 for all accidents but the record is very clear that the helicopter safety record is not as good as fixed wing by pretty much any metric you can think of.

the cost part is simple. In an twin engine airplane, you have two engines, two propellers and maybe a bit of hydraulics for the gear etc.. Simple. Now count the moving parts on a helicopter, gearboxes, axles, blades, rotorheads, etc etc... all those parts are lifed to a certain number of hours (sometimes not even high). That brings parts replacement cost as well as maintenance hours to replace those parts.
As one who flies both fixed and rotary wing, I still think that helicopter pilots are probably more "aware". My grandmother could fly a C172, but she couldn't fly an R22 even though with a bit of training it is absolute fun to fly. I'm also one of those who would for most of the times chose an engine out landing in a helicopter over an engine out landing in an airplane.
