Pfizer has a great marketing engine amongst the rest of the big pharma companies. Very early on, they realized that they should start developing applications that would be useful to their customers. One of the things that they decided to come up with was an application on the mobile phone that would tell you where to buy Robitussin. Not very useful as such unless you are a real Robitussin junkie and need the supply of this all the time no matter how much you travel. However, this was a great start off point since now they have come up with version 2.0 of the application that tells you which US state or location has the flu or cough/cold infections in progress. So, if you could plan your travel then it would make a great accessory to travel. Incidentally, you would also know where to buy Pfizer’s product too.
Great marketing. Good serial app development.
