Choose the right P, Q & M analogs

Your company expects the total smartphone market between 2007 and 2022 to be 2 billion devices after the 2007 launch.

Non-smart phones historically had p = .008 and q = .421. Looking at historical p and q values you notice that Color TV had half the p value of Black & White TV. People took time to replace their old TVs, so there were less "innovators". However, in the end, the imitators q stayed the same because everyone transitioned to Color TV. Thus, you expect smartphone innovators to be half of the regular cell phones yet the overall q to be the same.

Forecast the rest of the sales within a BASS model. Given the first four years of data choose the most applicable p, q and m.
