I TALKED to some high school students and reminisced how times have changed. When I graduated from high school , there was still no Internet, e-mail, cellphones, texting or even fax.

Thus, when we separated after high school, the only way to keep in touch was to write letters and send these through post.

At that time, when we wrote each other, we counted it fortunate if the recipients got it the next week and we got a reply within three or four weeks.

Now, with modern technology like texting and chatting, people get upset when they don’t get a reply within 30 seconds.

An old friend told me he enjoys watching movies from the 1950s and 1960s. Honestly, I’ve tried watching some old classics back then, even highly-rated movies, but I find them boring.

Moviemakers in the 21st century try to make sure their films are fast-paced and viewers are always kept in suspense. Many young people find old movies too dragging.

But even now, times continue to change. A recent survey found that most Internet users in the United States are spending less time on e-mail and portals like Yahoo and spending more time in social networking sites and games.

Thanks largely to social sites like Facebook, online games are now the second most time-consuming activity in the Web. The first, of course, is social networking. By this, you can generally see where the direction is online.

Social networks are changing the way people communicate and find information online. In fact, it is often through Facebook and Twitter that I know about the latest news–from a recent hurricane, to the death of a celebrity.

People are also spending more time streaming videos and movies.

In the mobile space, people are also changing their behaviors.

Before, I used to be texting a lot because it was the cheapest and most convenient thing to do. Now I text less and tend to connect with some people through online chat. Chat can be cheaper, especially if you are overseas. E-mails and online chat can be also almost free if you get one of those packages that have huge or unlimited data. With more and more smartphones offering the ability to email or chat, expect texting to slow down.

In fact, these changes in behavior are affecting cellular companies. PLDT-Smart and Globe saw a drop in revenues and profits as almost four out of five people already have cellphones and with the proliferation of unlimited call and text packages.

Sales reportedly fell about one percent in PLDT while Globe’s mobile phone subscribers reportedly fell two percent to roughly 25 million as of end of June. The revenue from text messaging also fell by 14 percent for PLDT, and the average monthly phone bill per customer reportedly declined 16 percent.
