Most actors are lucky to play one iconic role over their careers. LeVar Burton has played at least three. Besides his breakthrough role in 1977’s “Roots” and his career-defining turn as Lt. Commander Geordi La Forge in “Star Trek: The Next Generation,” for over 20 years, Burton was best known to a few generations of American children as the host of PBS’s “Reading Rainbow.” The series went off the air in 2005, but Burton keeps “Reading Rainbow” alive as an app and an educational company.

The next big tech company to release its earnings this week is Google. The company will report this afternoon. And the update for investors is all about Google’s bread and butter — advertising. Businesses still buy ads based on keywords like “teapot” or “crossbow,” but now, instead of bidding on one platform at a time, Google has been offering multiple platforms at once — tablets, phones, and PCs. So how’s that working out for them?
