Sega is reportedly close to buying Rovio Entertainment, according to The Wall Street Journal

The company that owns the Angry Birds mobile game franchise for $1 billion.

According to people who spoke with WSJ

Sega could be closing in on the big deal as early as next week.

It's amazing to think that Sega - specifically,

Its parent company Sega Sammy Holdings

Seeing the decline in popularity of Angry Birds games

Will want to spend that much on Rovio.

The original game was a huge success in 2009,

But the franchise has fallen since its 2014 peak,

When Rovio reported benefits and layoffs.
