@Bill
I think that whatever estimate is given for the upgrade market / aftermarket / specialist market / advanced product market size, or however we want to define the online community type of products (although these products also feature strongly in many stores), it can be attacked as being too low or too high. Certainly I was attacked in the past for saying that 'our' end of the market was about 10% and very firmly told that 'we' are about 2% of the market.
Several market research firms and publications like the WSJ regularly ask me to quote exact figures for various things, which is impossible. There have been times when several data sources seemed to agree regarding certain figures, but on the whole it is a guessing game. This year I've just told them to go away and work it out themselves, it is probably impossible to quote an accurate figure. One good reason for that is because no one knows the annual market growth; and since it is impossible for that to be lower than 40% for any given metric*, and could easily be 100% for some metrics, it means that any figure quoted is obsolete next month. In a market growing as fast as this one, who can possibly give an accurate figure at any time?
* 'Growth' is a flexible concept because someone might mean any of three metrics: market size, user numbers, or units sold. Which exactly is meant - because each could be very different? Probably, the user number will experience the lowest growth, and the units sold** will experience the highest growth, with market size somewhere between the two.
** 'Number of units sold' - a figure the market researchers are always desperate to try and pin down - is particularly hard to estimate in the ecig world. What exactly is meant: complete units sold in a box, disregarding the 4x volume of parts sold (batteries, cartos etc)? And what about the advanced product market area where people are buying vast quantities of generic batteries, assorted heads, and hundreds of thousands of gallons of refill liquid? It seems to me that in the e-cigarette area, the usual concept of 'units sold' is particularly hard to define.
The way I would try to figure out market size is as follows:
- Estimate the total turnover for mini ecig vendors based on turnover posted by the giant firms, plus estimated total turnover of all the smaller firms
- Estimate the total turnover for advanced product vendors based on turnover posted by the larger firms, plus estimated total turnover of all the smaller firms
- Add together, then add a fudge factor
For the minis: a year or so back the biggest vendor was reputed to be V2, with a turnover of $60m. Blu was at about half that. Others came in a bit lower than Blu. This year Blu/Lorillard are posting ~$50m per quarter so they have taken a massive leap - maybe 4x turnover this year, if that can be believed [1]. I guess you could estimate about $700m for the mini section of the market currently, from figures that are visible/guessable. Add 20% fudge factor: let's say $840m.
For the advanced product market, there aren't many vendors with an annual gross of over $10m, a few at $5m - $10m, and many around $0.5m to $1m. Dozens if not hundreds at <$0.1m. So $150m for this section? Add a fudge factor of 20% and it adds up to $180m.
So, what have we got: total ~$1bn ($1,020m), and the advanced market is 17.6%. Near enough to 20% I guess, so Bill is right if my guesses are right (or if they are right plus n% all round).
OK Bill you're right, especially if the advanced market is bigger than my guess (which, actually, is probably true).
There may be an issue with which category to put certain vendors in. For example there are valid arguments to put V4L (Vapor4Life) in either.
Then add whatever percentage of the US market you figure for the ROTW market, for a world total. Plus 50%? Plus 150%? Who knows.
[1] Caution: any sales figure published can generally be divided by two due to exaggeration - unless they are posting the same figure in their official company accounts. As far as I know, no ecig firm's PR sales figure ever lined up with what they told the IRS, in a manner of speaking. Also you can judge the honesty factor from claims about market share: company X says, "Our sales are $40m this year and we have 22% of the US market". Um, no, the market is probably approaching $1bn so, assuming your PR sales figure is anywhere near accurate (a big assumption), you have about 4% of the US market.
