Internet privacy is a plural concept; not exactly in the Orwellian sense of the term. Therefore, it is difficult to argue it in a single point reference. Databases have grown exponentially and of several orders of magnitude that was not possible previously. Technological advancements and big data number crunching has come of age. Similarly, despite rise of smartphones and associated applications, death of prevalent computing platform is highly exaggerated. Browsers remain central to access to internet.
The infamous browser wars led to Netscapes demise in the 90s followed by Google Chrome and Firefox leading the attack on Microsofts dominance. The advantage with corporations is huge advertising spend to foster better brand recall but is not necessarily better.

This was generated by tracking of cache via ETags, local Web application DOMStorage and Adobe Flash via Locally Stored Objects.

They are also able to target unique advertisements tailored to your use. It depends on individual users how much they trust a corporation to retain anonymous data. Although Do not Track headers have become fashionable (and controversial), the onus lies on the advertisers to honour it as a self policing model and not under legislative purview. This has become more problematic recently when Google has
