Technological change in the telecommunications industry started the day after the phone was invented. So there's a long history of innovation and improvements. I'd say today this is driven primarily by consumers and their needs and demands, and it's centred on the imagination of folks who see the opportunities out there.
We're probably more of an exception, not being a standard incumbent phone company. But as an industry, the incumbent phone companies traditionally haven't done a lot of direct investment themselves. I would say most of the investment in R and D is by suppliers, who are trying to keep ahead and develop new products and services to sell to the phone companies. Indirectly, we do a lot of investing in R and D, but it's mostly applied research and development that we do ourselves as a phone company.
