After a five year investigation of the search giant, European regulators are expected to launch an official antitrust case against Google tomorrow. The Wall Street Journal reports EU Commissioner for competition Margrethe Vestager will make the announcement tomorrow (Wednesday the 15th). Google will then be served with a "statement of objection" and charge sheet. At that point, the lawyers will begin legal wrangling that is sure to last years.

In the Google case, the EU is expected to allege that Mountain View unfairly promotes its own services over others in search. Google's share of the search market is even higher in the EU than in North America. If the EU and Google take this all the way, it could theoretically result in over $6 billion in fines. It's unlikely it would be anything that high, but Google might also have to abide by some sort of pro-competition agreement in the future.

This case will the be the largest for the EU Commission since the Microsoft investigation, which concluded over a decade ago. That case revolved around Microsoft bundling Media Player in Windows, which was seen as unfair to competitors like QuickTime and RealPlayer. Yes, really—times were very different. There was also an issue around server product interoperability. Microsoft was forced to release a version of Windows without Media Player, but of course that turned out to be essentially pointless.

The EU's case against Microsoft took six years to run its course (16 years if you count the full investigation). So nothing is changing tomorrow for Google, and I'm sure Mountain View will hire as many lawyers as it takes to get an outcome it can live with.

Google issues internal memo on EU case

Google will surely have an official statement when the EU announces the formal start of the case tomorrow, but a memo has already been sent out to Googlers that explains the company's position. This was obviously intended to be leaked, and it was to Recode.

The statement is quite long, so I'm going to put it in a collapsed PR box, even though it's not quite PR. One thing to note, Google expects an investigation of Android to be launched tomorrow as well. I imagine we'll hear about that in detail if it happens.
